49,Universal React,"One of the libraries to receive a huge amount of focus in 2015 has been ReactJS, a library created by Facebook for building user interfaces and web applications.
More generally we’ve seen an even greater rise in the number of applications built primarily on the client side with most of the logic implemented in JavaScript. One of the main issues with building an app in this way is that you immediately forgo any customers who might browse with JavaScript turned off, and you can also miss out on any robots that might visit your site to crawl it (such as Google’s search bots). Additionally, we gain a performance improvement by being able to render from the server rather than having to wait for all the JavaScript to be loaded and executed.
The good news is that this problem has been recognised and it is possible to build a fully featured client-side application that can be rendered on the server. The way in which these apps work is as follows:

The user visits www.yoursite.com and the server executes your JavaScript to generate the HTML it needs to render the page.
In the background, the client-side JavaScript is executed and takes over the duty of rendering the page.
The next time a user clicks, rather than being sent to the server, the client-side app is in control.
If the user doesn’t have JavaScript enabled, each click on a link goes to the server and they get the server-rendered content again.

This means you can still provide a very quick and snappy experience for JavaScript users without having to abandon your non-JS users. We achieve this by writing JavaScript that can be executed on the server or on the client (you might have heard this referred to as isomorphic) and using a JavaScript framework that’s clever enough handle server- or client-side execution. Currently, ReactJS is leading the way here, although Ember and Angular are both working on solutions to this problem.
It’s worth noting that this tutorial assumes some familiarity with React in general, its syntax and concepts. If you’d like a refresher, the ReactJS docs are a good place to start.
 Getting started
We’re going to create a tiny ReactJS application that will work on the server and the client. First we’ll need to create a new project and install some dependencies. In a new, blank directory, run:
npm init -y
npm install --save ejs express react react-router react-dom
That will create a new project and install our dependencies:

ejs is a templating engine that we’ll use to render our HTML on the server.
express is a small web framework we’ll run our server on.
react-router is a popular routing solution for React so our app can fully support and respect URLs.
react-dom is a small React library used for rendering React components.

We’re also going to write all our code in ECMAScript 6, and therefore need to install BabelJS and configure that too.
npm install --save-dev babel-cli babel-preset-es2015 babel-preset-react
Then, create a .babelrc file that contains the following:
{
  ""presets"": [""es2015"", ""react""]
}
What we’ve done here is install Babel’s command line interface (CLI) tool and configured it to transform our code from ECMAScript 6 (or ES2015) to ECMAScript 5, which is more widely supported. We’ll need the React transforms when we start writing JSX when working with React.
Creating a server
For now, our ExpressJS server is pretty straightforward. All we’ll do is render a view that says ‘Hello World’. Here’s our server code:
import express from 'express';
import http from 'http';

const app = express();

app.use(express.static('public'));

app.set('view engine', 'ejs');

app.get('*', (req, res) => {
  res.render('index');
});

const server = http.createServer(app);

server.listen(3003);
server.on('listening', () => {
  console.log('Listening on 3003');
});
Here we’re using ES6 modules, which I wrote about on 24 ways last year, if you’d like a reminder. We tell the app to render the index view on any GET request (that’s what app.get('*') means, the wildcard matches any route).
We now need to create the index view file, which Express expects to be defined in views/index.ejs:
<!DOCTYPE html>
<html>
  <head>
    <title>My App</title>
  </head>

  <body>
    Hello World
  </body>
</html>
Finally, we’re ready to run the server. Because we installed babel-cli earlier we have access to the babel-node executable, which will transform all your code before running it through node. Run this command:
./node_modules/.bin/babel-node server.js
And you should now be able to visit http://localhost:3003 and see ‘Hello World’ right there:

Building the React app
Now we’ll build the React application entirely on the server, before adding the client-side JavaScript right at the end. Our app will have two routes, / and /about which will both show a small amount of content. This will demonstrate how to use React Router on the server side to make sure our React app plays nicely with URLs.
Firstly, let’s update views/index.ejs. Our server will figure out what HTML it needs to render, and pass that into the view. We can pass a value into our view when we render it, and then use EJS syntax to tell it to output that data. Update the template file so the body looks like so:
<body>
  <%- markup %>
</body>
Next, we’ll define the routes we want our app to have using React Router. For now we’ll just define the index route, and not worry about the /about route quite yet. We could define our routes in JSX, but I think for server-side rendering it’s clearer to define them as an object. Here’s what we’re starting with:
const routes = {
  path: '',
  component: AppComponent,
  childRoutes: [
    {
      path: '/',
      component: IndexComponent
    }
  ]
}
These are just placed at the top of server.js, after the import statements. Later we’ll move these into a separate file, but for now they are fine where they are.
Notice how I define first that the AppComponent should be used at the '' path, which effectively means it matches every single route and becomes a container for all our other components. Then I give it a child route of /, which will match the IndexComponent. Before we hook these routes up with our server, let’s quickly define components/app.js and components/index.js. app.js looks like so:
import React from 'react';

export default class AppComponent extends React.Component {
  render() {
    return (
      <div>
        <h2>Welcome to my App</h2>
        { this.props.children }
      </div>
    );
  }
}
When a React Router route has child components, they are given to us in the props under the children key, so we need to include them in the code we want to render for this component. The index.js component is pretty bland:
import React from 'react';

export default class IndexComponent extends React.Component {
  render() {
    return (
      <div>
        <p>This is the index page</p>
      </div>
    );
  }
}
Server-side routing with React Router
Head back into server.js, and firstly we’ll need to add some new imports:
import React from 'react';
import { renderToString } from 'react-dom/server';
import { match, RoutingContext } from 'react-router';

import AppComponent from './components/app';
import IndexComponent from './components/index';
The ReactDOM package provides react-dom/server which includes a renderToString method that takes a React component and produces the HTML string output of the component. It’s this method that we’ll use to render the HTML from the server, generated by React. From the React Router package we use match, a function used to find a matching route for a URL; and RoutingContext, a React component provided by React Router that we’ll need to render. This wraps up our components and provides some functionality that ties React Router together with our app. Generally you don’t need to concern yourself about how this component works, so don’t worry too much.
Now for the good bit: we can update our app.get('*') route with the code that matches the URL against the React routes:
app.get('*', (req, res) => {
  // routes is our object of React routes defined above
  match({ routes, location: req.url }, (err, redirectLocation, props) => {
    if (err) {
      // something went badly wrong, so 500 with a message
      res.status(500).send(err.message);
    } else if (redirectLocation) {
      // we matched a ReactRouter redirect, so redirect from the server
      res.redirect(302, redirectLocation.pathname + redirectLocation.search);
    } else if (props) {
      // if we got props, that means we found a valid component to render
      // for the given route
      const markup = renderToString(<RoutingContext {...props} />);

      // render `index.ejs`, but pass in the markup we want it to display
      res.render('index', { markup })

    } else {
      // no route match, so 404. In a real app you might render a custom
      // 404 view here
      res.sendStatus(404);
    }
  });
});
We call match, giving it the routes object we defined earlier and req.url, which contains the URL of the request. It calls a callback function we give it, with err, redirectLocation and props as the arguments. The first two conditionals in the callback function just deal with an error occuring or a redirect (React Router has built in redirect support). The most interesting bit is the third conditional, else if (props). If we got given props and we’ve made it this far it means we found a matching component to render and we can use this code to render it:
...
} else if (props) {
  // if we got props, that means we found a valid component to render
  // for the given route
  const markup = renderToString(<RoutingContext {...props} />);

  // render `index.ejs`, but pass in the markup we want it to display
  res.render('index', { markup })
} else {
   ...
}
The renderToString method from ReactDOM takes that RoutingContext component we mentioned earlier and renders it with the properties required. Again, you need not concern yourself with what this specific component does or what the props are. Most of this is data that React Router provides for us on top of our components.
Note the {...props}, which is a neat bit of JSX syntax that spreads out our object into key value properties. To see this better, note the two pieces of JSX code below, both of which are equivalent:
<MyComponent a=""foo"" b=""bar"" />

// OR:

const props = { a: ""foo"", b: ""bar"" };
<MyComponent {...props} />
Running the server again
I know that felt like a lot of work, but the good news is that once you’ve set this up you are free to focus on building your React components, safe in the knowledge that your server-side rendering is working. To check, restart the server and head to http://localhost:3003 once more. You should see it all working!

Refactoring and one more route
Before we move on to getting this code running on the client, let’s add one more route and do some tidying up. First, move our routes object out into routes.js:
import AppComponent from './components/app';
import IndexComponent from './components/index';

const routes = {
  path: '',
  component: AppComponent,
  childRoutes: [
    {
      path: '/',
      component: IndexComponent
    }
  ]
}

export { routes };
And then update server.js. You can remove the two component imports and replace them with:
import { routes } from './routes';
Finally, let’s add one more route for ./about and links between them. Create components/about.js:
import React from 'react';

export default class AboutComponent extends React.Component {
  render() {
    return (
      <div>
        <p>A little bit about me.</p>
      </div>
    );
  }
}
And then you can add it to routes.js too:
import AppComponent from './components/app';
import IndexComponent from './components/index';
import AboutComponent from './components/about';

const routes = {
  path: '',
  component: AppComponent,
  childRoutes: [
    {
      path: '/',
      component: IndexComponent
    },
    {
      path: '/about',
      component: AboutComponent
    }
  ]
}

export { routes };
If you now restart the server and head to http://localhost:3003/about` you’ll see the about page!

For the finishing touch we’ll use the React Router link component to add some links between the pages. Edit components/app.js to look like so:
import React from 'react';
import { Link } from 'react-router';

export default class AppComponent extends React.Component {
  render() {
    return (
      <div>
        <h2>Welcome to my App</h2>
        <ul>
          <li><Link to='/'>Home</Link></li>
          <li><Link to='/about'>About</Link></li>
        </ul>
        { this.props.children }
      </div>
    );
  }
}
You can now click between the pages to navigate. However, everytime we do so the requests hit the server. Now we’re going to make our final change, such that after the app has been rendered on the server once, it gets rendered and managed in the client, providing that snappy client-side app experience.
Client-side rendering
First, we’re going to make a small change to views/index.ejs. React doesn’t like rendering directly into the body and will give a warning when you do so. To prevent this we’ll wrap our app in a div:
<body>
  <div id=""app""><%- markup %></div>
  <script src=""build.js""></script>
</body>
I’ve also added in a script tag to build.js, which is the file we’ll generate containing all our client-side code.
Next, create client-render.js. This is going to be the only bit of JavaScript that’s exclusive to the client side. In it we need to pull in our routes and render them to the DOM.
import React from 'react';
import ReactDOM from 'react-dom';
import { Router } from 'react-router';

import { routes } from './routes';

import createBrowserHistory from 'history/lib/createBrowserHistory';

ReactDOM.render(
  <Router routes={routes} history={createBrowserHistory()} />,
  document.getElementById('app')
)
The first thing you might notice is the mention of createBrowserHistory. React Router is built on top of the history module, a module that listens to the browser’s address bar and parses the new location. It has many modes of operation: it can keep track using a hashbang, such as http://localhost/#!/about (this is the default), or you can tell it to use the HTML5 history API by calling createBrowserHistory, which is what we’ve done. This will keep the URLs nice and neat and make sure the client and the server are using the same URL structure. You can read more about React Router and histories in the React Router documentation.
Finally we use ReactDOM.render and give it the Router component, telling it about all our routes, and also tell ReactDOM where to render, the #app element.
Generating build.js
We’re actually almost there! The final thing we need to do is generate our client side bundle. For this we’re going to use webpack, a module bundler that can take our application, follow all the imports and generate one large bundle from them. We’ll install it and babel-loader, a webpack plugin for transforming code through Babel.
npm install --save-dev webpack babel-loader
To run webpack we just need to create a configuration file, called webpack.config.js. Create the file in the root of our application and add the following code:
var path = require('path');
module.exports = {
  entry: path.join(process.cwd(), 'client-render.js'),
  output: {
    path: './public/',
    filename: 'build.js'
  },
  module: {
    loaders: [
      {
        test: /.js$/,
        loader: 'babel'
      }
    ]
  }
}
Note first that this file can’t be written in ES6 as it doesn’t get transformed. The first thing we do is tell webpack the main entry point for our application, which is client-render.js. We use process.cwd() because webpack expects an exact location – if we just gave it the string ‘client-render.js’, webpack wouldn’t be able to find it.
Next, we tell webpack where to output our file, and here I’m telling it to place the file in public/build.js. Finally we tell webpack that every time it hits a file that ends in .js, it should use the babel-loader plugin to transform the code first.
Now we’re ready to generate the bundle!
./node_modules/.bin/webpack
This will take a fair few seconds to run (on my machine it’s about seven or eight), but once it has it will have created public/build.js, a client-side bundle of our application. If you restart your server once more you’ll see that we can now navigate around our application without hitting the server, because React on the client takes over. Perfect!
The first bundle that webpack generates is pretty slow, but if you run webpack -w it will go into watch mode, where it watches files for changes and regenerates the bundle. The key thing is that it only regenerates the small pieces of the bundle it needs, so while the first bundle is very slow, the rest are lightning fast. I recommend leaving webpack constantly running in watch mode when you’re developing.
Conclusions
First, if you’d like to look through this code yourself you can find it all on GitHub. Feel free to raise an issue there or tweet me if you have any problems or would like to ask further questions.
Next, I want to stress that you shouldn’t use this as an excuse to build all your apps in this way. Some of you might be wondering whether a static site like the one we built today is worth its complexity, and you’d be right. I used it as it’s an easy example to work with but in the future you should carefully consider your reasons for wanting to build a universal React application and make sure it’s a suitable infrastructure for you.
With that, all that’s left for me to do is wish you a very merry Christmas and best of luck with your React applications!",2015,Jack Franklin,jackfranklin,2015-12-05T00:00:00+00:00,https://24ways.org/2015/universal-react/,code
54,Putting My Patterns through Their Paces,"Over the last few years, the conversation around responsive design has shifted subtly, focusing not on designing pages, but on patterns: understanding the small, reusable elements that comprise a larger design system. And given that many of those patterns are themselves responsive, learning to manage these small layout systems has become a big part of my work.
The thing is, the more pattern-driven work I do, the more I realize my design process has changed in a number of subtle, important ways. I suppose you might even say that pattern-driven design has, in a few ways, redesigned me.
Meet the Teaser
Here’s a recent example. A few months ago, some friends and I redesigned The Toast. (It was a really, really fun project, and we learned a lot.) Each page of the site is, as you might guess, stitched together from a host of tiny, reusable patterns. Some of them, like the search form and footer, are fairly unique, and used once per page; others are used more liberally, and built for reuse. The most prevalent example of these more generic patterns is the teaser, which is classed as, uh, .teaser. (Look, I never said I was especially clever.)
In its simplest form, a teaser contains a headline, which links to an article:

Fairly straightforward, sure. But it’s just the foundation: from there, teasers can have a byline, a description, a thumbnail, and a comment count. In other words, we have a basic building block (.teaser) that contains a few discrete content types – some required, some not. In fact, very few of those pieces need to be present; to qualify as a teaser, all we really need is a link and a headline. But by adding more elements, we can build slight variations of our teaser, and make it much, much more versatile.

        Nearly every element visible on this page is built out of our generic “teaser” pattern.
    
But the teaser variation I’d like to call out is the one that appears on The Toast’s homepage, on search results or on section fronts. In the main content area, each teaser in the list features larger images, as well as an interesting visual treatment: the byline and comment count were the most prominent elements within each teaser, appearing above the headline.

        The approved visual design of our teaser, as it appears on lists on the homepage and the section fronts.
    
And this is, as it happens, the teaser variation that gave me pause. Back in the old days – you know, like six months ago – I probably would’ve marked this module up to match the design. In other words, I would’ve looked at the module’s visual hierarchy (metadata up top, headline and content below) and written the following HTML:
<div class=""teaser"">
  <p class=""article-byline"">By <a href=""#"">Author Name</a></p>
  <a class=""comment-count"" href=""#"">126 <i>comments</i></a>
  <h1 class=""article-title""><a href=""#"">Article Title</a></h1>
  <p class=""teaser-excerpt"">Lorem ipsum dolor sit amet, consectetur…</p>
</div>
But then I caught myself, and realized this wasn’t the best approach.
Moving Beyond Layout
Since I’ve started working responsively, there’s a question I work into every step of my design process. Whether I’m working in Sketch, CSSing a thing, or researching a project, I try to constantly ask myself:

What if someone doesn’t browse the web like I do?

…Okay, that doesn’t seem especially fancy. (And maybe you came here for fancy.) But as straightforward as that question might seem, it’s been invaluable to so many aspects of my practice. If I’m working on a widescreen layout, that question helps me remember the constraints of the small screen; if I’m working on an interface that has some enhancements for touch, it helps me consider other input modes as I work. It’s also helpful as a reminder that many might not see the screen the same way I do, and that accessibility (in all its forms) should be a throughline for our work on the web.
And that last point, thankfully, was what caught me here. While having the byline and comment count at the top was a lovely visual treatment, it made for a terrible content hierarchy. For example, it’d be a little weird if the page was being read aloud in a speaking browser: the name of the author and the number of comments would be read aloud before the title of the article with which they’re associated.
That’s why I find it’s helpful to begin designing a pattern’s hierarchy before its layout: to move past the visual presentation in front of me, and focus on the underlying content I’m trying to support. In other words, if someone’s encountering my design without the CSS I’ve written, what should their experience be?
So I took a step back, and came up with a different approach:
<div class=""teaser"">
  <h1 class=""article-title""><a href=""#"">Article Title</a></h1>
  <h2 class=""article-byline"">By <a href=""#"">Author Name</a></h2>
  <p class=""teaser-excerpt"">
    Lorem ipsum dolor sit amet, consectetur…
    <a class=""comment-count"" href=""#"">126 <i>comments</i></a>
  </p>
</div>
Much, much better. This felt like a better match for the content I was designing: the headline – easily most important element – was at the top, followed by the author’s name and an excerpt. And while the comment count is visually the most prominent element in the teaser, I decided it was hierarchically the least critical: that’s why it’s at the very end of the excerpt, the last element within our teaser. And with some light styling, we’ve got a respectable-looking hierarchy in place:

Yeah, you’re right – it’s not our final design. But from this basic-looking foundation, we can layer on a bit more complexity. First, we’ll bolster the markup with an extra element around our title and byline:
<div class=""teaser"">
  <div class=""teaser-hed"">
    <h1 class=""article-title""><a href=""#"">Article Title</a></h1>
    <h2 class=""article-byline"">By <a href=""#"">Author Name</a></h2>
  </div>
  …
</div>
With that in place, we can use flexbox to tweak our layout, like so:
.teaser-hed {
  display: flex;
  flex-direction: column-reverse;
}
flex-direction: column-reverse acts a bit like a change in gravity within our teaser-hed element, vertically swapping its two children.

Getting closer! But as great as flexbox is, it doesn’t do anything for elements outside our container, like our little comment count, which is, as you’ve probably noticed, still stranded at the very bottom of our teaser.
Flexbox is, as you might already know, wonderful! And while it enjoys incredibly broad support, there are enough implementations of old versions of Flexbox (in addition to plenty of bugs) that I tend to use a feature test to check if the browser’s using a sufficiently modern version of flexbox. Here’s the one we used:
var doc = document.body || document.documentElement;
var style = doc.style;

if ( style.webkitFlexWrap == '' ||
    style.msFlexWrap == '' ||
    style.flexWrap == '' ) {
  doc.className += "" supports-flex"";
}
Eagle-eyed readers will note we could have used @supports feature queries to ask browsers if they support certain CSS properties, removing the JavaScript dependency. But since we wanted to serve the layout to IE we opted to write a little question in JavaScript, asking the browser if it supports flex-wrap, a property used elsewhere in the design. If the browser passes the test, then a class of supports-flex gets applied to our html element. And with that class in place, we can safely quarantine our flexbox-enabled layout from less-capable browsers, and finish our teaser’s design:
.supports-flex .teaser-hed {
  display: flex;
  flex-direction: column-reverse;
}
.supports-flex .teaser .comment-count {
  position: absolute;
  right: 0;
  top: 1.1em;
}
If the supports-flex class is present, we can apply our flexbox layout to the title area, sure – but we can also safely use absolute positioning to pull our comment count out of its default position, and anchor it to the top right of our teaser. In other words, the browsers that don’t meet our threshold for our advanced styles are left with an attractive design that matches our HTML’s content hierarchy; but the ones that pass our test receive the finished, final design.

And with that, our teaser’s complete.
Diving Into Device-Agnostic Design
This is, admittedly, a pretty modest application of flexbox. (For some truly next-level work, I’d recommend Heydon Pickering’s “Flexbox Grid Finesse”, or anything Zoe Mickley Gillenwater publishes.) And for such a simple module, you might feel like this is, well, quite a bit of work. And you’d be right! In fact, it’s not one layout, but two: a lightly styled content hierarchy served to everyone, with the finished design served conditionally to the browsers that can successfully implement it. But I’ve found that thinking about my design as existing in broad experience tiers – in layers – is one of the best ways of designing for the modern web. And what’s more, it works not just for simple modules like our teaser, but for more complex or interactive patterns as well.
Open video
    
        Even a simple search form can be conditionally enhanced, given a little layered thinking.
    
This more layered approach to interface design isn’t a new one, mind you: it’s been championed by everyone from Filament Group to the BBC. And with all the challenges we keep uncovering, a more device-agnostic approach is one of the best ways I’ve found to practice responsive design. As Trent Walton once wrote,

Like cars designed to perform in extreme heat or on icy roads, websites should be built to face the reality of the web’s inherent variability.

We have a weird job, working on the web. We’re designing for the latest mobile devices, sure, but we’re increasingly aware that our definition of “smartphone” is much too narrow. Browsers have started appearing on our wrists and in our cars’ dashboards, but much of the world’s mobile data flows over sub-3G networks. After all, the web’s evolution has never been charted along a straight line: it’s simultaneously getting slower and faster, with devices new and old coming online every day. With all the challenges in front of us, including many we don’t yet know about, a more device-agnostic, more layered design process can better prepare our patterns – and ourselves – for the future.

55,How Tabs Should Work,"Tabs in browsers (not browser tabs) are one of the oldest custom UI elements in a browser that I can think of. They’ve been done to death. But, sadly, most of the time I come across them, the tabs have been badly, or rather partially, implemented.
So this post is my definition of how a tabbing system should work, and one approach of implementing that.
But… tabs are easy, right?
I’ve been writing code for tabbing systems in JavaScript for coming up on a decade, and at one point I was pretty proud of how small I could make the JavaScript for the tabbing system:
var tabs = $('.tab').click(function () {
  tabs.hide().filter(this.hash).show();
}).map(function () {
  return $(this.hash)[0];
});

$('.tab:first').click();
Simple, right? Nearly fits in a tweet (ignoring the whole jQuery library…). Still, it’s riddled with problems that make it a far from perfect solution.
Requirements: what makes the perfect tab?

All content is navigable and available without JavaScript (crawler-compatible and low JS-compatible).
ARIA roles.
The tabs are anchor links that:

are clickable
have block layout
have their href pointing to the id of the panel element
use the correct cursor (i.e. cursor: pointer).

Since tabs are clickable, the user can open in a new tab/window and the page correctly loads with the correct tab open.
Right-clicking (and Shift-clicking) doesn’t cause the tab to be selected.
Native browser Back/Forward button correctly changes the state of the selected tab (think about it working exactly as if there were no JavaScript in place).

The first three points are all to do with the semantics of the markup and how the markup has been styled. I think it’s easy to do a good job by thinking of tabs as links, and not as some part of an application. Links are navigable, and they should work the same way other links on the page work.
The last three points are JavaScript problems. Let’s investigate that.
The shitmus test
Like a litmus test, here’s a couple of quick ways you can tell if a tabbing system is poorly implemented:

Change tab, then use the Back button (or keyboard shortcut) and it breaks
The tab isn’t a link, so you can’t open it in a new tab

These two basic things are, to me, the bare minimum that a tabbing system should have.
Why is this important?
The people who push their so-called native apps on users can’t have more reasons why the web sucks. If something as basic as a tab doesn’t work, obviously there’s more ammo to push a closed native app or platform on your users.
If you’re going to be a web developer, one of your responsibilities is to maintain established interactivity paradigms. This doesn’t mean don’t innovate. But it does mean: stop fucking up my scrolling experience with your poorly executed scroll effects. </rant> :breath:
URI fragment, absolute URL or query string?
A URI fragment (AKA the # hash bit) would be using mysite.com/config#content to show the content panel. A fully addressable URL would be mysite.com/config/content. Using a query string (by way of filtering the page): mysite.com/config?tab=content.
This decision really depends on the context of your tabbing system. For something like GitHub’s tabs to view a pull request, it makes sense that the full URL changes.
For our problem though, I want to solve the issue when the page doesn’t do a full URL update; that is, your regular run-of-the-mill tabbing system.
I used to be from the school of using the hash to show the correct tab, but I’ve recently been exploring whether the query string can be used. The biggest reason is that multiple hashes don’t work, and comma-separated hash fragments don’t make any sense to control multiple tabs (since it doesn’t actually link to anything).
For this article, I’ll keep focused on using a single tabbing system and a hash on the URL to control the tabs.
Markup
I’m going to assume subcontent, so my markup would look like this (yes, this is a cat demo…):
<ul class=""tabs"">
  <li><a class=""tab"" href=""#dizzy"">Dizzy</a></li>
  <li><a class=""tab"" href=""#ninja"">Ninja</a></li>
  <li><a class=""tab"" href=""#missy"">Missy</a></li>
</ul>

<div id=""dizzy"">
  <!-- panel content -->
</div>
<div id=""ninja"">
  <!-- panel content -->
</div>
<div id=""missy"">
  <!-- panel content -->
</div>
It’s important to note that in the markup the link used for an individual tab references its panel content using the hash, pointing to the id on the panel. This will allow our content to connect up without JavaScript and give us a bunch of features for free, which we’ll see once we’re on to writing the code.
URL-driven tabbing systems
Instead of making the code responsive to the user’s input, we’re going to exclusively use the browser URL and the hashchange event on the window to drive this tabbing system. This way we get Back button support for free.
With that in mind, let’s start building up our code. I’ll assume we have the jQuery library, but I’ve also provided the full code working without a library (vanilla, if you will), but it depends on relatively new (polyfillable) tech like classList and dataset (which generally have IE10 and all other browser support).
Note that I’ll start with the simplest solution, and I’ll refactor the code as I go along, like in places where I keep calling jQuery selectors.
function show(id) {
  // remove the selected class from the tabs,
  // and add it back to the one the user selected
  $('.tab').removeClass('selected').filter(function () {
    return (this.hash === id);
  }).addClass('selected');

  // now hide all the panels, then filter to
  // the one we're interested in, and show it
  $('.panel').hide().filter(id).show();
}

$(window).on('hashchange', function () {
  show(location.hash);
});

// initialise by showing the first panel
show('#dizzy');
This works pretty well for such little code. Notice that we don’t have any click handlers for the user and the Back button works right out of the box.
However, there’s a number of problems we need to fix:

The initialised tab is hard-coded to the first panel, rather than what’s on the URL.
If there’s no hash on the URL, all the panels are hidden (and thus broken).
If you scroll to the bottom of the example, you’ll find a “top” link; clicking that will break our tabbing system.
I’ve purposely made the page long, so that when you click on a tab, you’ll see the page scrolls to the top of the tab. Not a huge deal, but a bit annoying.

From our criteria at the start of this post, we’ve already solved items 4 and 5. Not a terrible start. Let’s solve items 1 through 3 next.
Using the URL to initialise correctly and protect from breakage
Instead of arbitrarily picking the first panel from our collection, the code should read the current location.hash and use that if it’s available.
The problem is: what if the hash on the URL isn’t actually for a tab?
The solution here is that we need to cache a list of known panel IDs. In fact, well-written DOM scripting won’t continuously search the DOM for nodes. That is, when the show function kept calling $('.tab').each(...) it was wasteful. The result of $('.tab') should be cached.
So now the code will collect all the tabs, then find the related panels from those tabs, and we’ll use that list to double the values we give the show function (during initialisation, for instance).
// collect all the tabs
var tabs = $('.tab');

// get an array of the panel ids (from the anchor hash)
var targets = tabs.map(function () {
  return this.hash;
}).get();

// use those ids to get a jQuery collection of panels
var panels = $(targets.join(','));

function show(id) {
  // if no value was given, let's take the first panel
  if (!id) {
    id = targets[0];
  }
  // remove the selected class from the tabs,
  // and add it back to the one the user selected
  tabs.removeClass('selected').filter(function () {
    return (this.hash === id);
  }).addClass('selected');

  // now hide all the panels, then filter to
  // the one we're interested in, and show it
  panels.hide().filter(id).show();
}

$(window).on('hashchange', function () {
  var hash = location.hash;
  if (targets.indexOf(hash) !== -1) {
    show(hash);
  }
});

// initialise
show(targets.indexOf(location.hash) !== -1 ? location.hash : '');
The core of working out which tab to initialise with is solved in that last line: is there a location.hash? Is it in our list of valid targets (panels)? If so, select that tab.
The second breakage we saw in the original demo was that clicking the “top” link would break our tabs. This was due to the hashchange event firing and the code didn’t validate the hash that was passed. Now this happens, the panels don’t break.
So far we’ve got a tabbing system that:

Works without JavaScript.
Supports right-click and Shift-click (and doesn’t select in these cases).
Loads the correct panel if you start with a hash.
Supports native browser navigation.
Supports the keyboard.

The only annoying problem we have now is that the page jumps when a tab is selected. That’s due to the browser following the default behaviour of an internal link on the page. To solve this, things are going to get a little hairy, but it’s all for a good cause.
Removing the jump to tab
You’d be forgiven for thinking you just need to hook a click handler and return false. It’s what I started with. Only that’s not the solution. If we add the click handler, it breaks all the right-click and Shift-click support.
There may be another way to solve this, but what follows is the way I found – and it works. It’s just a bit… hairy, as I said.
We’re going to strip the id attribute off the target panel when the user tries to navigate to it, and then put it back on once the show code starts to run. This change will mean the browser has nowhere to navigate to for that moment, and won’t jump the page.
The change involves the following:

Add a click handle that removes the id from the target panel, and cache this in a target variable that we’ll use later in hashchange (see point 4).
In the same click handler, set the location.hash to the current link’s hash. This is important because it forces a hashchange event regardless of whether the URL actually changed, which prevents the tabs breaking (try it yourself by removing this line).
For each panel, put a backup copy of the id attribute in a data property (I’ve called it old-id).
When the hashchange event fires, if we have a target value, let’s put the id back on the panel.

These changes result in this final code:
/*global $*/

// a temp value to cache *what* we're about to show
var target = null;

// collect all the tabs
var tabs = $('.tab').on('click', function () {
  target = $(this.hash).removeAttr('id');

  // if the URL isn't going to change, then hashchange
  // event doesn't fire, so we trigger the update manually
  if (location.hash === this.hash) {
    // but this has to happen after the DOM update has
    // completed, so we wrap it in a setTimeout 0
    setTimeout(update, 0);
  }
});

// get an array of the panel ids (from the anchor hash)
var targets = tabs.map(function () {
  return this.hash;
}).get();

// use those ids to get a jQuery collection of panels
var panels = $(targets.join(',')).each(function () {
  // keep a copy of what the original el.id was
  $(this).data('old-id', this.id);
});

function update() {
  if (target) {
    target.attr('id', target.data('old-id'));
    target = null;
  }

  var hash = window.location.hash;
  if (targets.indexOf(hash) !== -1) {
    show(hash);
  }
}

function show(id) {
  // if no value was given, let's take the first panel
  if (!id) {
    id = targets[0];
  }
  // remove the selected class from the tabs,
  // and add it back to the one the user selected
  tabs.removeClass('selected').filter(function () {
    return (this.hash === id);
  }).addClass('selected');

  // now hide all the panels, then filter to
  // the one we're interested in, and show it
  panels.hide().filter(id).show();
}

$(window).on('hashchange', update);

// initialise
if (targets.indexOf(window.location.hash) !== -1) {
  update();
} else {
  show();
}
This version now meets all the criteria I mentioned in my original list, except for the ARIA roles and accessibility. Getting this support is actually very cheap to add.
ARIA roles
This article on ARIA tabs made it very easy to get the tabbing system working as I wanted.
The tasks were simple:

Add aria-role set to tab for the tabs, and tabpanel for the panels.
Set aria-controls on the tabs to point to their related panel (by id).
I use JavaScript to add tabindex=0 to all the tab elements.
When I add the selected class to the tab, I also set aria-selected to true and, inversely, when I remove the selected class I set aria-selected to false.
When I hide the panels I add aria-hidden=true, and when I show the specific panel I set aria-hidden=false.

And that’s it. Very small changes to get full sign-off that the tabbing system is bulletproof and accessible.
Check out the final version (and the non-jQuery version as promised).
In conclusion
There’s a lot of tab implementations out there, but there’s an equal amount that break the browsing paradigm and the simple linkability of content. Clearly there’s a special hell for those tab systems that don’t even use links, but I think it’s clear that even in something that’s relatively simple, it’s the small details that make or break the user experience.
Obviously there are corners I’ve not explored, like when there’s more than one set of tabs on a page, and equally whether you should deliver the initial markup with the correct tab selected. I think the answer lies in using query strings in combination with hashes on the URL, but maybe that’s for another year!",2015,Remy Sharp,remysharp,2015-12-22T00:00:00+00:00,https://24ways.org/2015/how-tabs-should-work/,code
57,Cooking Up Effective Technical Writing,"Merry Christmas! May your preparations for this festive season of gluttony be shaping up beautifully. By the time you read this I hope you will have ordered your turkey, eaten twice your weight in Roses/Quality Street (let’s not get into that argument), and your Christmas cake has been baked and is now quietly absorbing regular doses of alcohol.
Some of you may be reading this and scoffing Of course! I’ve also made three batches of mince pies, a seasonal chutney and enough gingerbread men to feed the whole street! while others may be laughing Bake? Oh no, I can’t cook to save my life.
For beginners, recipes are the step-by-step instructions that hand-hold us through the cooking process, but even as a seasoned expert you’re likely to refer to a recipe at some point. Recipes tell us what we need, what to do with it, in what order, and what the outcome will be. It’s the documentation behind our ideas, and allows us to take the blueprint for a tasty morsel and to share it with others so they can recreate it. In fact, this is a little like the open source documentation and tutorials that we put out there, similarly aiming to guide other developers through our creations.
The ‘just’ification of documentation
Lately it feels like we’re starting to consider the importance of our words, and the impact they can have on others. Brad Frost warned us of the dangers of “Just” when it comes to offering up solutions to queries:

“Just use this software/platform/toolkit/methodology…”
“Just” makes me feel like an idiot. “Just” presumes I come from a specific background, studied certain courses in university, am fluent in certain technologies, and have read all the right books, articles, and resources. “Just” is a dangerous word.
“Just” by Brad Frost

I can really empathise with these sentiments. My relationship with code started out as many good web tales do, with good old HTML, CSS and JavaScript. University years involved some time with Perl, PHP, Java and C. In my first job I worked primarily with ColdFusion, a bit of ActionScript, some classic  ASP and pinch of Java. I’d do a bit of PHP outside work every now and again. .NET came in, but we never really got on, and eventually I started learning some Ruby, Python and Node. It was a broad set of learnings, and I enjoyed the similarities and differences that came with new languages. I don’t develop day in, day out any more, and my interests and work have evolved over the years, away from full-time development and more into architecture and strategy. But I still make things, and I still enjoy learning.
I have often found myself bemoaning the lack of tutorials or courses that cater for the middle level – someone who may be learning a new language, but who has enough programming experience under their belt to not need to revise the concepts of how loops or objects work, and is perfectly adept at googling the syntax for getting a substring. I don’t want snippets out of context; I want an understanding of architectural principles, of the strengths and weaknesses, of the type of applications that work well with the language.
I’m caught in the place between snoozing off when ‘Using the Instagram API with Ruby’ hand-holds me through what REST is, and feeling like I’m stupid and need to go back to dev school when I can’t get my environment and dependencies set up, let alone work out how I’m meant to get any code to run.
It’s seems I’m not alone with this – Erin McKean seems to have been here too:

“Some tutorials (especially coding tutorials) like to begin things in media res. Great for a sense of dramatic action, bad for getting to “Step 1” without tears. It can be really discouraging to fire up a fresh terminal window only to be confronted by error message after error message because there were obligatory steps 0.1.0 through 0.9.9 that you didn’t even know about.”
“Tips for Learning What You Don’t Know You Don’t Know” by Erin McKean

I’m sure you’ve been here too. Many tutorials suffer badly from the fabled ‘how to draw an owl’-itis.

It’s the kind of feeling you can easily get when sifting through recipes as well as with code. Far from being the simple instructions that let us just follow along, they too can be a minefield. Fall in too low and you may be skipping over an explanation of what simmering is, or set your sights too high and you may get stuck at the point where you’re trying to sous vide a steak using your bathtub and a Ziploc bag.
Don’t be a turkey, use your loaf!
My mum is a great cook in my eyes (aren’t all mums?). I love her handcrafted collection of gathered recipes from over the years, including the one below, which is a great example of how something may make complete sense to the writer, but could be impermeable to a reader.

Depending on your level of baking knowledge, you may ask: What’s SR flour? What’s a tsp? Should I use salted or unsalted butter? Do I use sticks of cinnamon or ground? Why is chopped chocolate better? How do I cream things? How big should the balls be? How well is “well spaced”? How much leeway do I have for “(ish!!)”? Does the “20” on the other cookie note mean I’ll end up with twenty? At any point, making a wrong call could lead to rubbish cookies, and lead to someone heading down the path of an I can’t cook mentality.
You may be able to cook (or follow recipes), but you may not understand the local terms for ingredients, may not be able to acquire something and need to know what kind of substitutes you can use, or may need to actually do some prep before you jump into the main bit.
However, if we look at good examples of recipes, I think there’s a lot we can apply when it comes to technical writing on the web. I’ve written before about the benefit of breaking documentation into small, reusable parts, and this will help us, but we can also take it a bit further. Here are my five top tips for better technical writing.
1. Structure and standardise your information
Think of the structure of a recipe. We very often have some common elements and they usually follow roughly the same format. We have standards and conventions that allow us to understand very quickly what a recipe is and how it should be used. 

Great recipes help their chefs know what they need to get ready in advance, both in terms of buying ingredients and putting together their kit. They then talk through the process, using appropriate language, and without making assumptions that the person can fill in any gaps for themselves; they explain why things are done the way they are. The best recipes may also suggest how you can take what you’ve done and put your own spin on it. For instance, a good recipe for the simple act of boiling an egg will explain cooking time in relation to your preference for yolk gooiness. There are also different flavour combinations to try, accompaniments, or presentation suggestions. 
By breaking down your technical writing into similar sections, you can help your audience understand the elements they’ll be working with, what they need to do once they have these, and how they can move on from your self-contained illustration.
Title
      
        Ensure your title is suitably descriptive and representative of the result. Getting Started with Python perhaps isn’t as helpful as Learn Python: General Syntax and Basics.
      
    Result
      
        Many recipes include a couple of lines as an overview of what you’ll end up with, and many include a photo of the finished dish. With our technical writing we can do the same:
        In this tutorial we’re going to learn how to set up our development environment, and we’ll then undertake some exercises to explore the general syntax, finishing by building a mini calculator.
      
    Ingredients
      
        What are the components we’ll be working with, whether in terms of versions, environment, languages or the software packages and libraries you’ll need along the way? Listing these up front gives the reader a great summary of the things they’ll be using, and any gotchas.
        Being able to provide a small amount of supporting information will also help less experienced users. Ideally, explain briefly what things are and why we’re using it.
      
    Prep
      
        As we heard from Erin above, not fully understanding the prep needed can be a huge source of frustration. Attempting to run a code snippet without context will often lead to failure when the prerequisites and process aren’t clear. Be sure to include information around any environment set-up, installation or config you’ll need to have done before you start.
Stu Robson’s Simple Sass documentation aims to do this before getting into specifics, although ideally this would also include setting up Sass itself.
      
    Instructions
      
The body of the tutorial itself is the whole point of our writing. The next four tips will hopefully make your tutorial much more successful.
      
    Variations
      
        Like our ingredients section, as important as explaining why we’re using something in this context is, it’s also great to explain alternatives that could be used instead, and the impact of doing so.
        Perhaps go a step further, explaining ways that people can change what you have done in your tutorial/readme for use in different situations, or to provide further reading around next steps. What happens if they want to change your static array of demo data to use JSON, for instance? By giving some thought to follow-up questions, you can better support your readers.
        While not in a separate section, the source code for GreenSock’s GSAP JS basics explains:
        We’ll use a window.onload for simplicity, but typically it is best to use either jQuery’s $(document).ready() or $(window).load() or cross-browser event listeners so that you’re not limited to one.
        Keep in mind to both:
        Explain what variations are possible.
          Explain why certain options may be more desirable than others in different situations.
        
    
2. Small, reusable components
Reusable components are for life, not just for Christmas, and they’re certainly not just for development. If you start to apply the structure above to your writing, you’re probably going to keep coming across the same elements: Do I really have to explain how to install Sass and Node.js again, Sally? The danger with more clarity is that our writing becomes bloated and overly convoluted for advanced readers, those who don’t need to be told how to beat an egg for the hundredth time. 
Instead, by making our writing reusable and modular, and by creating smaller, central resources, we can provide context and extra detail where needed without diluting our core message. These could be references we create, or those already created well by others.

This recipe for katsudon makes use of this concept. Rather than explaining how to make tonkatsu or dashi stock, these each have their own page. Once familiar, more advanced readers will likely skip over the instructions for the component parts.

3. Provide context to aid accessibility
Here I’m talking about accessibility in the broadest sense. Small, isolated snippets can be frustrating to those who don’t fully understand the wider context of how our examples work.
Showing an exciting standalone JavaScript function is great, but giving someone the full picture of how and when this is called, and how it should be included in relation to other HTML and CSS is even better. Giving your readers the ability to view a big picture version, and ideally the ability to download a full version of the source, will help to reduce some of the frustrations of trying to get your component to work in their set-up. 
4. Be your own tech editor
A good editor can be invaluable to your work, and wherever possible I’d recommend that you try to get a neutral party to read over your writing. This may not always be possible, though, and you may need to rely on yourself to cast a critical eye over your work.
There are many tips out there around general editing, including printing out your work onto paper, or changing the font size: both will force your eyes to review it in a new light. Beyond this, I’d like to encourage you to think about the following:

Explain what things are. For example, instead of referencing Grunt, in the first instance perhaps reference “Grunt (a JavaScript task runner that minimises repetitive activities through automation).”
Explain how you get things, even if this is a link to official installers and documentation. Don’t leave your readers having to search.
Why are you using this approach/technology over other options?
What happens if I use something else? What depends on this?
Avoid exclusionary lingo or acronyms.

Airbnb’s JavaScript Style Guide includes useful pointers around their reasoning:

Use computed property names when creating objects with dynamic property names.
Why? They allow you to define all the properties of an object in one place.

The language we use often makes assumptions, as we saw with “just”. An article titled “ES6 for Beginners” is hugely ambiguous: is this truly for beginner coders, or actually for people who have a good pre-existing understanding of JavaScript but are new to these features? Review your writing with different types of readers in mind. How might you confuse or mislead them? How can you better answer their questions?
This doesn’t necessarily mean supporting everyone – your audience may need to have advanced skills – but even if you’re providing low-level, deep-dive, reference material, trying not to make assumptions or take shortcuts will hopefully lead to better, clearer writing.
5. A picture is worth a thousand words…
…or even better: use a thousand pictures, stitched together into a quick video or animated GIF. People learn in different ways. Just as recipes often provide visual references or a video to work along with, providing your technical information with alternative demonstrations can really help get your point across. Your audience will be able to see exactly what you’re doing, what they should expect as interaction responses, and what the process looks like at different points.
There are many, many options for recording your screen, including QuickTime Player on Mac OS X (File → New Screen Recording), GifGrabber, or Giffing Tool on Windows.
Paul Swain, a UX designer, uses GIFs to provide additional context within his documentation, improving communication:

“My colleagues (from across the organisation) love animated GIFs. Any time an interaction is referenced, it’s accompanied by a GIF and a shared understanding of what’s being designed. The humble GIF is worth so much more than a thousand words; and it’s great for cats.”
Paul Swain


Next time you’re cooking up some instructions for readers, think back to what we can learn from recipes to help make your writing as accessible as possible. Use structure, provide reusable bitesize morsels, give some context, edit wisely, and don’t scrimp on the GIFs. And above all, have a great Christmas!",2015,Sally Jenkinson,sallyjenkinson,2015-12-18T00:00:00+00:00,https://24ways.org/2015/cooking-up-effective-technical-writing/,content
58,Beyond the Style Guide,"Much like baking a Christmas cake, designing for the web involves creating an experience in layers. Starting with a solid base that provides the core experience (the fruit cake), we can add further layers, each adding refinement (the marzipan) and delight (the icing).
Don’t worry, this isn’t a misplaced cake recipe, but an evaluation of modular design and the role style guides can play in acknowledging these different concerns, be they presentational or programmatic.
The auteur’s style guide
Although trained as a graphic designer, it was only when I encountered the immediacy of the web that I felt truly empowered as a designer. Given a desire to control every aspect of the resulting experience, I slowly adopted the role of an auteur, exploring every part of the web stack: front-end to back-end, and everything in between. A few years ago, I dreaded using the command line. Today, the terminal is a permanent feature in my Dock.
In straddling the realms of graphic design and programming, it’s the point at which they meet that I find most fascinating, with each dicipline valuing the creation of effective systems, be they for communication or code efficiency. Front-end style guides live at this intersection, demonstrating both the modularity of code and the application of visual design.
Painting by numbers
In our rush to build modular systems, design frameworks have grown in popularity. While enabling quick assembly, these come at the cost of originality and creative expression – perhaps one reason why we’re seeing the homogenisation of web design.
In editorial design, layouts should accentuate content and present it in an engaging manner. Yet on the web we see a practice that seeks templated predictability. In ‘Design Machines’ Travis Gertz argued that (emphasis added):

Design systems still feel like a novelty in screen-based design. We nerd out over grid systems and modular scales and obsess over style guides and pattern libraries. We’re pretty good at using them to build repeatable components and site-wide standards, but that’s sort of where it ends. […] But to stop there is to ignore the true purpose and potential of a design system.

Unless we consider how interface patterns fully embrace the design systems they should be built upon, style guides may exacerbate this paint-by-numbers approach, encouraging conformance and suppressing creativity.
Anatomy of a button
Let’s take a look at that most canonical of components, the button, and consider what we might wish to document and demonstrate in a style guide.
The different layers of our button component.
Content
The most variable aspect of any component. Content guidelines will exert the most influence here, dictating things like tone of voice (whether we should we use stiff, formal language like ‘Submit form’, or adopt a more friendly tone, perhaps ‘Send us your message’) and appropriate language. For an internationalised interface, this may also impact word length and text direction or orientation.
Structure
HTML provides a limited vocabulary which we can use to structure content and add meaning. For interactive elements, the choice of element can also affect its behaviour, such as whether a button submits form data or links to another page:
<button type=""submit"">Button text</button>
<a href=""/index.html"">Button text</a>
Note: One of the reasons I prefer to use <button> instead of <input type=“button”>, besides allowing the inclusion of content other than text, is that it has a markup structure similar to links, therefore keeping implementation differences to a minimum.
We should also think about each component within the broader scope of our particular product. For this we can employ a further vocabulary, which can be expressed by adding values to the class attribute. For a newspaper, we might use names like lede, standfirst and headline, while a social media application might see us reach for words like stream, action or avatar.
Presentation
The appearance of a component can never be considered in isolation. Informed by its relationship to other elements, style guides may document different stylistic variations of a component, even if the underlying function remains unchanged: primary and secondary button styles, for example.
Behaviour
A component can exhibit various states: blank, loading, partial, error and ideal, and a style guide should reflect that. Our button component is relatively simple, yet even here we need to consider hover, focused, active and disabled states.
Transcending layers
This overview reinforces Ethan’s note from earlier in this series:

I’ve found that thinking about my design as existing in broad experience tiers – in layers – is one of the best ways of designing for the modern web.

While it’s tempting to describe a component as series of layers, certain aspects will transcend several of these. The accessibility of a component, for example, may influence the choice of language, the legibility of text, colour contrast and which affordances are provided in different states.
Visual design language: documenting the missing piece
Even given this small, self-contained component, we can see several concerns at play, and in reviewing our button it seems we have most things covered. However, a few questions remain unanswered. Why does it have a blue background? Why are the borders 2px thick, with a radius of 4px? Why are we using that font, at that size and with that weight?
These questions can be answered by our visual design language. More than a set of type choices and colour palettes, a design language can dicate common measures, ratios and the resulting grid(s) these influence. Ideally governed by a set of broader design principles, it can also inform an illustration style, the type of photography sourced or commissioned, and the behaviour of any animations.
Whereas a style guide ensures conformity, having it underpinned by an effective design language will allow for flexibility; only by knowing the rules can you know how to break them!
Type pairings in the US Web Design Standards guide.
For a style guide to thoroughly articulate a visual design system, the spectrum of choices it allows for should be acknowledged. A fantastic example of this can be found in the US Web Design Standards. By virtue of being a set of standards designed to apply to a number of different sites, this guide offers a range of type pairings (that take into account performance considerations) and provides primary, secondary and tertiary palette relationships, with shades and tones thereof:

A visual language in code form
Properly documenting our design language in a style guide is a good start, yet even better if it can be expressed in code. This is where CSS preprocessors become a powerful ally.
In Sass, methods like mixins and maps can help us represent relationships between values. Variables (and CSS variables) extend the vocabulary provided natively by CSS, meaning we can describe patterns in terms of our own visual language. These tools effectively become an interface to our design system. Furthermore, they help maintain a separation of concerns, with visual presentation remaining where it should be: in our style sheets.
Take this simple example, an article summary on a website counting down the best Christmas movies:
The design for our simple component example.
Our markup is as follows, using appropriate semantic HTML elements and incorporating the vocabulary from our collection of design patterns (expressed using the BEM methodology):
<article class=""summary"">
    <h1 class=""summary__title"">
        <a href=""scrooged.html"">
            <span class=""summary__position"">12</span>
            Scrooged (1988)
        </a>
    </h1>

    <div class=""summary__body"">
        <p>It’s unlikely that Bill Murray could ever have got through his career without playing a version of Scrooge…</p>
    </div>

    <footer class=""summary__meta"">
        <strong>Director:</strong> Richard Donner<br/>
        <strong>Stars:</strong> Bill Murray, Buddy Hackett, Karen Allen
    </footer>
</article>
We can then describe the presentation of this HTML by using Sass maps to define our palettes, mixins to include predefined font metrics, and variables to recall common measurements:
.summary {
    margin-bottom: ($baseline * 4)
}

.summary__title {
    @include font-family(display-serif);
    @include font-size(title);
    color: palette(neutral, dark);
    margin-bottom: ($baseline * 4);
    border-top: $rule-height solid palette(primary, purple);
    padding-top: ($baseline * 2);
}

.summary__position {
    @include font-family(display-sans, 300);
    color: palette(neutral, mid);
}

.summary__body {
    @include font-family(text-serif);
    @include font-size(body);
    margin-bottom: ($baseline * 2);
}

.summary__meta {
    @include font-family(text-sans);
    @include font-size(caption);
}
Of course, this is a simplistic example for the purposes of demonstration. However, such thinking was employed at a much larger scale at the Guardian. Using a set of Sass components, complex patterns could be described using a language familar to everyone on the product team, be they a designer, developer or product owner:

Unlocking possibility
Alongside tools like preprocessors, newer CSS layout modules like flexbox and grid layout mean the friction we’ve long been accustomed to when creating layouts on the web is no longer present, and the full separation of presentation from markup is now possible. Now is the perfect time for graphic designers to advocate design systems that these developments empower, and ensure they’re fully represented in both documentation and code. That way, together, we can build systems that allow for greater visual expression. After all, there’s more than one way to bake a Christmas cake.",2015,Paul Lloyd,paulrobertlloyd,2015-12-16T00:00:00+00:00,https://24ways.org/2015/beyond-the-style-guide/,design
60,What’s Ahead for Your Data in 2016?,"Who owns your data? Who decides what can you do with it? Where can you store it? What guarantee do you have over your data’s privacy? Where can you publish your work? Can you adapt software to accommodate your disability? Is your tiny agency subject to corporate regulation? Does another country have rights over your intellectual property?
If you aren’t the kind of person who is interested in international politics, I hate to break it to you: in 2016 the legal foundations which underpin our work on the web are being revisited in not one but three major international political agreements, and every single one of those questions is up for grabs. These agreements – the draft EU Data Protection Regulation (EUDPR), the Trans-Pacific Partnership (TPP), and the draft Transatlantic Trade and Investment Partnership (TTIP) – stand poised to have a major impact on your data, your workflows, and your digital rights. While some proposed changes could protect the open web for the future, other provisions would set the internet back several decades.
In this article we will review the issues you need to be aware of as a digital professional. While each of these agreements covers dozens of topics ranging from climate change to food safety, we will focus solely on the aspects which pertain to the work we do on the web.
The Trans-Pacific Partnership
The Trans-Pacific Partnership (TPP) is a free trade agreement between the US, Japan, Malaysia, Vietnam, Singapore, Brunei, Australia, New Zealand, Canada, Mexico, Chile and Peru – a bloc comprising 40% of the world’s economy. The agreement is expected to be signed by all parties, and thereby to come into effect, in 2016. This agreement is ostensibly about the bloc and its members working together for their common interests. However, the latest draft text of the TPP, which was formulated entirely in secret, has only been made publicly available on a Medium blog published by the U.S. Trade Representative which features a patriotic banner at the top proclaiming “TPP: Made in America.” The message sent about who holds the balance of power in this agreement, and whose interests it will benefit, is clear.
By far the most controversial area of the TPP has centred around the provisions on intellectual property. These include copyright terms of up to 120 years, mandatory takedowns of allegedly infringing content in response to just one complaint regardless of that complaint’s validity, heavy and disproportionate penalties for alleged violations, and – most frightening of all – government seizures of equipment allegedly used for copyright violations. All of these provisions have been raised without regard for the fact that a trade agreement is not the appropriate venue to negotiate intellectual property law.
Other draft TPP provisions would restrict the digital rights of people with disabilities by banning the workarounds they use every day. These include no exemptions for the adaptations of copywritten works for use in accessible technology (such as text-to-speech in ebook readers), a ban on circumventing DRM or digital locks in order to convert a file to an accessible format, and requiring the takedown of adapted works, such as a video with added subtitles, even if that adaptation would normally have fallen under the definition of fair use.
The e-commerce provisions would prohibit data localisation, the practice of requiring data to be physically stored on servers within a country’s borders. Data localisation is growing in popularity following the Snowden revelations, and some of your own personal data may have been recently “localised” in response to the Safe Harbor verdict. Prohibiting data localisation through the TPP would address the symptom but not the cause.
The Electronic Frontier Foundation has published an excellent summary of the digital rights issues raised by the agreement along with suggested actions American readers can take to speak out.
Transatlantic Trade and Investment Partnership
TTIP stands for the Transatlantic Trade and Investment Partnership, a draft free trade agreement between the United States and the EU. The plan has been hugely controversial and divisive, and the internet and digital provisions of the draft form just a small part of that contention.
The most striking digital provision of TTIP is an attempt to circumvent and override European data protection law. As EDRI, a European digital rights organisation, noted:

“the US proposal would authorise the transfer of EU citizens’ personal data to any country, trumping the EU data protection framework, which ensures that this data can only be transferred in clearly defined circumstances. For years, the US has been trying to bypass the default requirement for storage of personal data in the EU. It is therefore not surprising to see such a proposal being {introduced} in the context of the trade negotiations.”

This draft provision was written before the Safe Harbor data protection agreement between the EU and US was invalidated by the Court of Justice of the European Union. In other words, there is no longer any protective agreement in place, and our data is as vulnerable as this political situation. However, data protection is a matter of its own law, the acting Data Protection Directive and the draft EU Data Protection Reform. A trade agreement, be it the TTIP or the TPP, is not the appropriate place to revamp a law on data protection.
Other digital law issues raised by TTIP include the possibility of renegotiating standards on encryption (which in practice means lowering them) and renegotiating intellectual property rights such as copyright. The spectre of net neutrality has even put in an appearance, with an attempt to introduce rules on access to the internet itself being introduced as provisions.
TTIP is still under discussion, and this month the EU trade representative said that “we agreed to further intensify our work during 2016 to help negotiations move forward rapidly.” This has been cleverly worded: this means the agreement has little chance of being passed or coming into effect in 2016, which buys civil society more precious time to speak out.
The EU Data Protection Regulation
On 15 December 2015 the European Commission announced their agreement on the text of the draft General Data Protection Regulation. This law will replace its predecessor, the EU Data Protection Regulation of 1995, which has done a remarkable job of protecting data privacy across the continent throughout two decades of constant internet evolution.
The goal of the reform process has been to return power over data, and its uses, to citizens. Users will have more control over what data is captured about them, how it is used, how it is retained, and how it can be deleted. Businesses and digital professionals, in turn, will have to restructure their relationships with client and customer data. Compliance obligations will increase, and difficult choices will have to be made. However, this time should be seen as an opportunity to rethink our relationship with data. After Snowden, Schrems, and Safe Harbor, it is clear that we cannot go back to the way things were before. In an era of where every one of our heartbeats is recorded on a wearable device and uploaded to a surveilled data centre in another country, the need for reform has never been more acute.
While texts of the draft GDPR are available, there is not enough mulled wine in the world that will help you get through them. Instead, the law firm Fieldfisher Waterhouse has produced this helpful infographic which will give you a good idea of the changes we can expect to see (view full size):

The most surprising outcome announced on 15 December was the new regulation’s teeth. Under the new law, companies that fail to heed the updated data protection rules will face fines of up to 4% of their global turnover. Additionally, the law expands the liability for data protection to both the controller (the company hosting the data) and the data processor (the company using the data). The new law will also introduce a one-stop shop for resolving concerns over data misuse. Companies will no longer be able to headquarter their European operations in countries which are perceived to have relatively light-touch data protection enforcement (that means you, Ireland) as a means of automatically rejecting any complaints filed by citizens outside that country.
For digital professionals, the most immediate concern is analytics. In fact, I am going to make a prediction: in 2016 we will begin to see the same misguided war on analytics that we saw on cookies. By increasing the legal liabilities for both data processors and controllers – in other words, the company providing the analytics as well as the site administrator studying them – the new regulation risks creating disproportionate burdens as well as the same “guilt by association” risks we saw in 2012. There have already been statements made by some within the privacy community that analytics are tracking, and tracking is surveillance, therefore analytics are evil. Yet “just don’t use analytics,” as was suggested by one advocate, is simply not an option. European regulators should consult with the web community to gain a clear understanding of why analytics are vital to everyday site administrators, and must find a happy medium that protects users’ data without criminalising every website by default. No one wants a repeat of the crisis of consent, as well as the scaremongering, caused by the cookie law.
Assuming the text is adopted in 2016, the new EU Data Protection Regulation would not come into effect until 2018. We have a considerable challenge ahead, but we also have plenty of time to get it right.",2015,Heather Burns,heatherburns,2015-12-21T00:00:00+00:00,https://24ways.org/2015/whats-ahead-for-your-data-in-2016/,business
65,The Accessibility Mindset,"Accessibility is often characterized as additional work, hard to learn and only affecting a small number of people. Those myths have no logical foundation and often stem from outdated information or misconceptions.
Indeed, it is an additional skill set to acquire, quite like learning new JavaScript frameworks, CSS layout techniques or new HTML elements. But it isn’t particularly harder to learn than those other skills.
A World Health Organization (WHO) report on disabilities states that,

[i]ncluding children, over a billion people (or about 15% of the world’s population) were estimated to be living with disability.

Being disabled is not as unusual as one might think. Due to chronic health conditions and older people having a higher risk of disability, we are also currently paving the cowpath to an internet that we can still use in the future.
Accessibility has a very close relationship with usability, and advancements in accessibility often yield improvements in the usability of a website. Websites are also more adaptable to users’ needs when they are built in an accessible fashion.
Beyond the bare minimum
In the time of table layouts, web developers could create code that passed validation rules but didn’t adhere to the underlying semantic HTML model. We later developed best practices, like using lists for navigation, and with HTML5 we started to wrap those lists in nav elements. Working with accessibility standards is similar. The Web Content Accessibility Guidelines (WCAG) 2.0 can inform your decision to make websites accessible and can be used to test that you met the success criteria. What it can’t do is measure how well you met them. 
W3C developed a long list of techniques that can be used to make your website accessible, but you might find yourself in a situation where you need to adapt those techniques to be the most usable solution for your particular problem.
The checkbox below is implemented in an accessible way: The input element has an id and the label associated with the checkbox refers to the input using the for attribute. The hover area is shown with a yellow background and a black dotted border:
Open video
    
The label is clickable and the checkbox has an accessible description. Job done, right? Not really. Take a look at the space between the label and the checkbox:
Open video
    
The gutter is created using a right margin which pushes the label to the right. Users would certainly expect this space to be clickable as well. The simple solution is to wrap the label around the checkbox and the text:
Open video
    
You can also set the label to display:block; to further increase the clickable area:
Open video
    
And while we’re at it, users might expect the whole box to be clickable anyway. Let’s apply the CSS that was on a wrapping div element to the label directly:
Open video
    
The result enhances the usability of your form element tremendously for people with lower dexterity, using a voice mouse, or using touch interfaces. And we only used basic HTML and CSS techniques; no JavaScript was added and not one extra line of CSS.
<form action=""#"">  
    <label for=""uniquecheckboxid"">
      <input type=""checkbox"" name=""checkbox"" id=""uniquecheckboxid"" />
      Checkbox 4
    </label>
</form>  
Button Example
The button below looks like a typical edit button: a pencil icon on a real button element. But if you are using a screen reader or a braille keyboard, the button is just read as “button” without any indication of what this button is for.
Open video
    A screen reader announcing a button. Contains audio.
The code snippet shows why the button is not properly announced:
<button>
  <span class=""icon icon-pencil""></span>
</button>
An icon font is used to display the icon and no text alternative is given. A possible solution to this problem is to use the title or aria-label attributes, which solves the alternative text use case for screen reader users:
Open video
    A screen reader announcing a button with a title.
However, screen readers are not the only way people with and without disabilities interact with websites. For example, users can reset or change font families and sizes at will. This helps many users make websites easier to read, including people with dyslexia. Your icon font might be replaced by a font that doesn’t include the glyphs that are icons. Additionally, the icon font may not load for users on slow connections, like on mobile phones inside trains, or because users decided to block external fonts altogether. The following screenshots show the mobile GitHub view with and without external fonts:
The mobile GitHub view with and without external fonts.
Even if the title/aria-label approach was used, the lack of visual labels is a barrier for most people under those circumstances. One way to tackle this is using the old-fashioned img element with an appropriate alt attribute, but surprisingly not every browser displays the alternative text visually when the image doesn’t load.
<button>
  <img src=""icon-pencil.svg"" alt=""Edit"">
</button>
Providing always visible text is an alternative that can work well if you have the space. It also helps users understand the meaning of the icons.
<button>
  <span class=""icon icon-pencil""></span> Edit
</button>
This also reads just fine in screen readers:
Open video
    A screen reader announcing the revised button.
Clever usability enhancements don’t stop at a technical implementation level. Take the BBC iPlayer pages as an example: when a user navigates the “captioned videos” or “audio description” categories and clicks on one of the videos, captions or audio descriptions are automatically switched on. Small things like this enhance the usability and don’t need a lot of engineering resources. It is more about connecting the usability dots for people with disabilities. Read more about the BBC iPlayer accessibility case study.
More information
W3C has created several documents that make it easier to get the gist of what web accessibility is and how it can benefit everyone. You can find out “How People with Disabilities Use the Web”, there are “Tips for Getting Started” for developers, designers and content writers. And for the more seasoned developer there is a set of tutorials on web accessibility, including information on crafting accessible forms and how to use images in an accessible way.
Conclusion
You can only produce a web project with long-lasting accessibility if accessibility is not an afterthought. Your organization, your division, your team need to think about accessibility as something that is the foundation of your website or project. It needs to be at the same level as performance, code quality and design, and it needs the same attention. Users often don’t notice when those fundamental aspects of good website design and development are done right. But they’ll always know when they are implemented poorly.
If you take all this into consideration, you can create accessibility solutions based on the available data and bring accessibility to people who didn’t know they’d need it:

In this video from the latest Apple keynote, the Apple TV is operated by voice input through a remote. When the user asks “What did she say?” the video jumps back fifteen seconds and captions are switched on for a brief time. All three, the remote, voice input and captions have their roots in assisting people with disabilities. Now they benefit everyone.",2015,Eric Eggert,ericeggert,2015-12-17T00:00:00+00:00,https://24ways.org/2015/the-accessibility-mindset/,code
67,What I Learned about Product Design This Year,"2015 was a humbling year for me. In September of 2014, I joined a tiny but established startup called SproutVideo as their third employee and first designer. The role interests me because it affords the opportunity to see how design can grow a solid product with a loyal user-base into something even better. 
The work I do now could also have a real impact on the brand and user experience of our product for years to come, which is a thrilling prospect in an industry where much of what I do feels small and temporary. I got in on the ground floor of something special: a small, dedicated, useful company that cares deeply about making video hosting effortless and rewarding for our users.
I had (and still have) grand ideas for what thoughtful design can do for a product, and the smaller-scale product design work I’ve done or helped manage over the past few years gave me enough eager confidence to dive in head first. Readers who have experience redesigning complex existing products probably have a knowing smirk on their face right now. As I said, it’s been humbling. A year of focused product design, especially on the scale we are trying to achieve with our small team at SproutVideo, has taught me more than any projects in recent memory. I’d like to share a few of those lessons.
Product design is very different from marketing design
The majority of my recent work leading up to SproutVideo has been in marketing design. These projects are so fun because their aim is to communicate the value of the product in a compelling and memorable way. In order to achieve this goal, I spent a lot of time thinking about content strategy, responsive design, and how to create striking visuals that tell a story. These are all pursuits I love.
Product design is a different beast. When designing a homepage, I can employ powerful imagery, wild gradients, and somewhat-quirky fonts. When I began redesigning the SproutVideo product, I wanted to draw on all the beautiful assets I’ve created for our marketing materials, but big gradients, textures, and display fonts made no sense in this new context.
That’s because the product isn’t about us, and it isn’t about telling our story. Product design is about getting out of the way so people can do their job. The visual design is there to create a pleasant atmosphere for people to work in, and to help support the user experience. Learning to take “us” out of the equation took some work after years of creating gorgeous imagery and content for the sales-driven side of businesses.
I’ve learned it’s very valuable to design both sides of the experience, because marketing and product design flex different muscles. If you’re currently in an environment where the two are separate, consider switching teams in 2016. Designing for product when you’ve mostly done marketing, or vice versa, will deepen your knowledge as a designer overall. You’ll face new unexpected challenges, which is the only way to grow.
Product design can not start with what looks good on Dribbble
I have an embarrassing confession: when I began the redesign, I had a secret goal of making something that would look gorgeous in my portfolio. I have a collection of product shots that I admire on Dribbble; examples of beautiful dashboards and widgets and UI elements that look good enough to frame. I wanted people to feel the same way about the final outcome of our redesign. Mistakenly, this was a factor in my initial work. I opened Photoshop and crafted pixel-perfect static buttons and form elements and color palettes that — when applied to our actual product — looked like a toddler beauty pageant. It added up to a lot of unusable shininess, noise, and silliness.
I was disappointed; these elements seemed so lovely in isolation, but in context, they felt tacky and overblown. I realized: I’m not here to design the world’s most beautiful drop down menu. Good design has nothing to do with ego, but in my experience designers are, at least a little bit, secret divas. I’m no exception. I had to remind myself that I am not working in service of a bigger Dribbble following or to create the most Pinterest-ing work. My function is solely to serve the users — to make life a little better for the good people who keep my company in business.
This meant letting go of pixel-level beauty to create something bigger and harder: a system of elements that work together in harmony in many contexts. The visual style exists to guide the users. When done well, it becomes a language that users understand, so when they encounter a new feature or have a new goal, they already feel comfortable navigating it. This meant stripping back my gorgeous animated menu into something that didn’t detract from important neighboring content, and could easily fit in other parts of the app. In order to know what visual style would support the users, I had to take a wider view of the product as a whole.
Just accept that designing a great product – like many worthwhile pursuits – is initially laborious and messy
Once I realized I couldn’t start by creating the most Dribbble-worthy thing, I knew I’d have to begin with the unglamorous, frustrating, but weirdly wonderful work of mapping out how the product’s content could better be structured. Since we’re redesigning an existing product, I assumed this would be fairly straightforward: the functionality was already in place, and my job was just to structure it in a more easily navigable way.
I started by handing off a few wireframes of the key screens to the developer, and that’s when the questions began rolling in: “If we move this content into a modal, how will it affect this similar action here?” “What happens if they don’t add video tags, but they do add a description?” “What if the user has a title that is 500 characters long?” “What if they want their video to be private to some users, but accessible to others?”.
How annoying (but really, fantastic) that people use our product in so many ways. Turns out, product design isn’t about laying out elements in the most ideal scenario for the user that’s most convenient for you. As product designers, we have to foresee every outcome, and anticipate every potential user need.
Which brings me to another annoying epiphany: if you want to do it well, and account for every user, product design is so much more snarly and tangled than you’d expect going in. I began with a simple goal: to improve the experience on just one of our key product pages. However, every small change impacts every part of the product to some degree, and that impact has to be accounted for. Every decision is based on assumptions that have to be tested; I test my assumptions by observing users, talking to the team, wireframing, and prototyping. Many of my assumptions are wrong. There are days when it’s incredibly frustrating, because an elegant solution for users with one goal will complicate life for users with another goal. It’s vital to solve as many scenarios as possible, even though this is slow, sometimes mind-bending work.
As a side bonus, wireframing and prototyping every potential state in a product is tedious, but your developers will thank you for it. It’s not their job to solve what happens when there’s an empty state, error, or edge case. Showing you’ve accounted for these scenarios will win a developer’s respect; failing to do so will frustrate them.
When you’ve created and tested a system that supports user needs, it will be beautiful
Remember what I said in the beginning about wanting to create a Dribbble-worthy product? When I stopped focusing on the visual details of the design (color, spacing, light and shadow, font choices) and focused instead on structuring the content to maximize usability and delight, a beautiful design began to emerge naturally.
I began with grayscale, flat wireframes as a strategy to keep me from getting pulled into the visual style before the user experience was established. As I created a system of elements that worked in harmony, the visual style choices became obvious. Some buttons would need to be brighter and sit off the page to help the user spot important actions. Some elements would need line separators to create a hierarchy, where others could stand on their own as an emphasized piece of content. As the user experience took shape, the visual style emerged naturally to support it. The result is a product that feels beautiful to use, because I was thoughtful about the experience first.

A big takeaway from this process has been that my assumptions will often be proven wrong. My assumptions about how to design a great product, and how users will interact with that product, have been tested and revised repeatedly. At SproutVideo we’re about to undertake the biggest test of our work; we’re going to launch a small part of the product redesign to our users. If I’ve learned anything, it’s that I will continue to be humbled by the ongoing effort of making the best product I can, which is a wonderful thing.
Next year, I hope you all get to do work that takes you out of our comfort zone. Be regularly confounded and embarrassed by your wrong assumptions, learn from them, and come back and tell us what you learned in 2016.",2015,Meagan Fisher,meaganfisher,2015-12-14T00:00:00+00:00,https://24ways.org/2015/what-i-learned-about-product-design-this-year/,design
68,"Grid, Flexbox, Box Alignment: Our New System for Layout","Three years ago for 24 ways 2012, I wrote an article about a new CSS layout method I was excited about. A specification had emerged, developed by people from the Internet Explorer team, bringing us a proper grid system for the web. In 2015, that Internet Explorer implementation is still the only public implementation of CSS grid layout. However, in 2016 we should be seeing it in a new improved form ready for our use in browsers.
Grid layout has developed hidden behind a flag in Blink, and in nightly builds of WebKit and, latterly, Firefox. By being developed in this way, breaking changes could be safely made to the specification as no one was relying on the experimental implementations in production work.
Another new layout method has emerged over the past few years in a more public and perhaps more painful way. Shipped prefixed in browsers, The flexible box layout module (flexbox) was far too tempting for developers not to use on production sites. Therefore, as changes were made to the specification, we found ourselves with three different flexboxes, and browser implementations that did not match one another in completeness or in the version of specified features they supported. 
Owing to the different ways these modules have come into being, when I present on grid layout it is often the very first time someone has heard of the specification. A question I keep being asked is whether CSS grid layout and flexbox are competing layout systems, as though it might be possible to back the loser in a CSS layout competition. The reality, however, is that these two methods will sit together as one system for doing layout on the web, each method playing to certain strengths and serving particular layout tasks. 
If there is to be a loser in the battle of the layouts, my hope is that it will be the layout frameworks that tie our design to our markup. They have been a necessary placeholder while we waited for a true web layout system, but I believe that in a few years time we’ll be easily able to date a website to circa 2015 by seeing <div class=""row""> or <div class=""col-md-3""> in the markup.
In this article, I’m going to take a look at the common features of our new layout systems, along with a couple of examples which serve to highlight the differences between them.
To see the grid layout examples you will need to enable grid in your browser. The easiest thing to do is to enable the experimental web platform features flag in Chrome. Details of current browser support can be found here. 
Relationship
Items only become flex or grid items if they are a direct child of the element that has display:flex, display:grid or display:inline-grid applied. Those direct children then understand themselves in the context of the complete layout. This makes many things possible. It’s the lack of relationship between elements that makes our existing layout methods difficult to use. If we float two columns, left and right, we have no way to tell the shorter column to extend to the height of the taller one. We have expended a lot of effort trying to figure out the best way to make full-height columns work, using techniques that were never really designed for page layout.
At a very simple level, the relationship between elements means that we can easily achieve full-height columns. In flexbox:
See the Pen Flexbox equal height columns by rachelandrew (@rachelandrew) on CodePen.

And in grid layout (requires a CSS grid-supporting browser):
See the Pen Grid equal height columns by rachelandrew (@rachelandrew) on CodePen.

Alignment
Full-height columns rely on our flex and grid items understanding themselves as part of an overall layout. They also draw on a third new specification: the box alignment module. If vertical centring is a gift you’d like to have under your tree this Christmas, then this is the box you’ll want to unwrap first.
The box alignment module takes the alignment and space distribution properties from flexbox and applies them to other layout methods. That includes grid layout, but also other layout methods. Once implemented in browsers, this specification will give us true vertical centring of all the things.
Our examples above achieved full-height columns because the default value of align-items is stretch. The value ensured our columns stretched to the height of the tallest. If we want to use our new vertical centring abilities on all items, we would set align-items:center on the container. To align one flex or grid item, apply the align-self property.
The examples below demonstrate these alignment properties in both grid layout and flexbox. The portrait image of Widget the cat is aligned with the default stretch. The other three images are aligned using different values of align-self.
Take a look at an example in flexbox:
See the Pen Flexbox alignment by rachelandrew (@rachelandrew) on CodePen.

And also in grid layout (requires a CSS grid-supporting browser):
See the Pen Grid alignment by rachelandrew (@rachelandrew) on CodePen.

The alignment properties used with CSS grid layout.
Fluid grids
A cornerstone of responsive design is the concept of fluid grids.

“[…]every aspect of the grid—and the elements laid upon it—can be expressed as a proportion relative to its container.”
—Ethan Marcotte, “Fluid Grids”

The method outlined by Marcotte is to divide the target width by the context, then use that value as a percentage value for the width property on our element.
h1 {
  margin-left: 14.575%; /* 144px / 988px = 0.14575 */
  width: 70.85%; /* 700px / 988px = 0.7085 */
}
In more recent years, we’ve been able to use calc() to simplify this (at least, for those of us able to drop support for Internet Explorer 8). However, flexbox and grid layout make fluid grids simple.
The most basic of flexbox demos shows this fluidity in action. The justify-content property – another property defined in the box alignment module – can be used to create an equal amount of space between or around items. As the available width increases, more space is assigned in proportion.
In this demo, the list items are flex items due to display:flex being added to the ul. I have given them a maximum width of 250 pixels. Any remaining space is distributed equally between the items as the justify-content property has a value of space-between.
See the Pen Flexbox: justify-content by rachelandrew (@rachelandrew) on CodePen.

For true fluid grid-like behaviour, your new flexible friends are flex-grow and flex-shrink. These properties give us the ability to assign space in proportion.
The flexbox flex property is a shorthand for:

flex-grow
flex-shrink
flex-basis

The flex-basis property sets the default width for an item. If flex-grow is set to 0, then the item will not grow larger than the flex-basis value; if flex-shrink is 0, the item will not shrink smaller than the flex-basis value.

flex: 1 1 200px: a flexible box that can grow and shrink from a 200px basis.
flex: 0 0 200px: a box that will be 200px and cannot grow or shrink.
flex: 1 0 200px: a box that can grow bigger than 200px, but not shrink smaller.

In this example, I have a set of boxes that can all grow and shrink equally from a 100 pixel basis.
See the Pen Flexbox: flex-grow by rachelandrew (@rachelandrew) on CodePen.

What I would like to happen is for the first element, containing a portrait image, to take up less width than the landscape images, thus keeping it more in proportion. I can do this by changing the flex-grow value. By giving all the items a value of 1, they all gain an equal amount of the available space after the 100 pixel basis has been worked out.
If I give them all a value of 3 and the first box a value of 1, the other boxes will be assigned three parts of the available space while box 1 is assigned only one part. You can see what happens in this demo:
See the Pen Flexbox: flex-grow by rachelandrew (@rachelandrew) on CodePen.

Once you understand flex-grow, you should easily be able to grasp how the new fraction unit (fr, defined in the CSS grid layout specification) works. Like flex-grow, this unit allows us to assign available space in proportion. In this case, we assign the space when defining our track sizes.
In this demo (which requires a CSS grid-supporting browser), I create a four-column grid using the fraction unit to define my track sizes. The first track is 1fr in width, and the others 2fr.
grid-template-columns: 1fr 2fr 2fr 2fr;
See the Pen Grid fraction units by rachelandrew (@rachelandrew) on CodePen.

The four-track grid.
Separation of concerns
My younger self petitioned my peers to stop using tables for layout and to move to CSS. One of the rallying cries of that movement was the concept of separating our source and content from how they were displayed. It was something of a failed promise given the tools we had available: the display leaked into the markup with the need for redundant elements to cope with browser bugs, or visual techniques that just could not be achieved without supporting markup.
Browsers have improved, but even now we can find ourselves compromising the ideal document structure so we can get the layout we want at various breakpoints. In some ways, the situation has returned to tables-for-layout days. Many of the current grid frameworks rely on describing our layout directly in the markup. We add divs for rows, and classes to describe the number of desired columns. We nest these constructions of divs inside one another.
Here is a snippet from the Bootstrap grid examples – two columns with two nested columns:
<div class=""row"">
  <div class=""col-md-8"">
    .col-md-8
    <div class=""row"">
      <div class=""col-md-6"">
        .col-md-6
      </div>
      <div class=""col-md-6"">
        .col-md-6
      </div>
    </div>
  </div>
  <div class=""col-md-4"">
    .col-md-4
  </div>
</div>
Not a million miles away from something I might have written in 1999.
<table>
  <tr>
    <td class=""col-md-8"">
      .col-md-8
      <table>
        <tr>
          <td class=""col-md-6"">
            .col-md-6
          </td>
          <td class=""col-md-6"">
            .col-md-6
          </td>
        </tr>
      </table>
    </td>
    <td class=""col-md-4"">
      .col-md-4
    </td>
  </tr>
</table>
Grid and flexbox layouts do not need to be described in markup. The layout description happens entirely in the CSS, meaning that elements can be moved around from within the presentation layer.
Flexbox gives us the ability to reverse the flow of elements, but also to set the order of elements with the order property. This is demonstrated here, where Widget the cat is in position 1 in the source, but I have used the order property to display him after the things that are currently unimpressive to him.
See the Pen Flexbox: order by rachelandrew (@rachelandrew) on CodePen.

Grid layout takes this a step further. Where flexbox lets us set the order of items in a single dimension, grid layout gives us the ability to position things in two dimensions: both rows and columns. Defined in the CSS, this positioning can be changed at any breakpoint without needing additional markup. Compare the source order with the display order in this example (requires a CSS grid-supporting browser):
See the Pen Grid positioning in two dimensions by rachelandrew (@rachelandrew) on CodePen.

Laying out our items in two dimensions using grid layout.
As these demos show, a straightforward way to decide if you should use grid layout or flexbox is whether you want to position items in one dimension or two. If two, you want grid layout.
A note on accessibility and reordering
The issues arising from this powerful ability to change the way items are ordered visually from how they appear in the source have been the subject of much discussion. The current flexbox editor’s draft states

“Authors must use order only for visual, not logical, reordering of content. Style sheets that use order to perform logical reordering are non-conforming.”
—CSS Flexible Box Layout Module Level 1, Editor’s Draft (3 December 2015)

This is to ensure that non-visual user agents (a screen reader, for example) can rely on the document source order as being correct. Take care when reordering that you do so from the basis of a sound document that makes sense in terms of source order. Avoid using visual order to convey meaning.
Automatic content placement with rules
Having control over the order of items, or placing items on a predefined grid, is nice. However, we can often do that already with one method or another and we have frameworks and tools to help us. Tools such as Susy mean we can even get away from stuffing our markup full of grid classes. However, our new layout methods give us some interesting new possibilities.
Something that is useful to be able to do when dealing with content coming out of a CMS or being pulled from some other source, is to define a bunch of rules and then say, “Display this content, using these rules.”
As an example of this, I will leave you with a Christmas poem displayed in a document alongside Widget the cat and some of the decorations that are bringing him no Christmas cheer whatsoever.
The poem is displayed first in the source as a set of paragraphs. I’ve added a class identifying each of the four paragraphs but they are displayed in the source as one text. Below that are all my images, some landscape and some portrait; I’ve added a class of landscape to the landscape ones.
The mobile-first grid is a single column and I use line-based placement to explicitly position my poem paragraphs. The grid layout auto-placement rules then take over and place the images into the empty cells left in the grid.
At wider screen widths, I declare a four-track grid, and position my poem around the grid, keeping it in a readable order.
I also add rules to my landscape class, stating that these items should span two tracks. Once again the grid layout auto-placement rules position the rest of my images without my needing to position them. You will see that grid layout takes items out of source order to fill gaps in the grid. It does this because I have set the property grid-auto-flow to dense. The default is sparse meaning that grid will not attempt this backfilling behaviour.
Take a look and play around with the full demo (requires a CSS grid layout-supporting browser):
See the Pen Grid auto-flow with rules by rachelandrew (@rachelandrew) on CodePen.

The final automatic placement example.
My wish for 2016
I really hope that in 2016, we will see CSS grid layout finally emerge from behind browser flags, so that we can start to use these features in production — that we can start to move away from using the wrong tools for the job.
However, I also hope that we’ll see developers fully embracing these tools as the new system that they are. I want to see people exploring the possibilities they give us, rather than trying to get them to behave like the grid systems of 2015. As you discover these new modules, treat them as the new paradigm that they are, get creative with them. And, as you find the edges of possibility with them, take that feedback to the CSS Working Group. Help improve the layout systems that will shape the look of the future web.

71,Upping Your Web Security Game,"When I started working in web security fifteen years ago, web development looked very different. The few non-static web applications were built using a waterfall process and shipped quarterly at best, making it possible to add security audits before every release; applications were deployed exclusively on in-house servers, allowing Info Sec to inspect their configuration and setup; and the few third-party components used came from a small set of well-known and trusted providers. And yet, even with these favourable conditions, security teams were quickly overwhelmed and called for developers to build security in.
If the web security game was hard to win before, it’s doomed to fail now. In today’s web development, every other page is an application, accepting inputs and private data from users; software is built continuously, designed to eliminate manual gates, including security gates; infrastructure is code, with servers spawned with little effort and even less security scrutiny; and most of the code in a typical application is third-party code, pulled in through open source repositories with rarely a glance at who provided them.
Security teams, when they exist at all, cannot solve this problem. They are vastly outnumbered by developers, and cannot keep up with the application’s pace of change. For us to have a shot at making the web secure, we must bring security into the core. We need to give it no less attention than that we give browser compatibility, mobile design or web page load times. More broadly, we should see security as an aspect of quality, expecting both ourselves and our peers to address it, and taking pride when we do it well.
Where To Start?
Embracing security isn’t something you do overnight.
A good place to start is by reviewing things you’re already doing – and trying to make them more secure. Here are three concrete steps you can take to get going.
HTTPS
Threats begin when your system interacts with the outside world, which often means HTTP. As is, HTTP is painfully insecure, allowing attackers to easily steal and manipulate data going to or from the server. HTTPS adds a layer of crypto that ensures the parties know who they’re talking to, and that the information exchanged can be neither modified nor sniffed.
HTTPS is relevant to any site. If your non-HTTPS site holds opinions, reading it may get your users in trouble with employers or governments. If your users believe what you say, attackers can modify your non-HTTPS to take advantage of and abuse that trust. If you want to use new browser technologies like HTTP2 and service workers, your site will need to be HTTPS. And if you want to be discovered on the web, using HTTPS can help your Google ranking. For more details on why I think you should make the switch to HTTPS, check out this post, these slides and this video.
Using HTTPS is becoming easier and cheaper. Here are a few free tools that can help:

Get free and easy HTTPS delivery from Cloudflare (be sure to use “Full SSL”!)
Get a free and automation-friendly certificate from Let’s Encrypt (now in open beta).
Test how well your HTTPS is set up using SSLTest.

Other vendors and platforms are rapidly simplifying and reducing the cost of their HTTPS offering, as demand and importance grows.
Two-Factor Authentication
The most sensitive data is usually stored behind a login, and the authentication process is the primary gate in front of this data. Making this process secure has many aspects, including using HTTPS when accepting credentials, having a strong password policy, never storing the password, and more.
All of these are important, but the best single step to boost your authentication security is to introduce two-factor authentication (2FA). Adding 2FA usually means prompting users for an additional one-time code when logging in, which they get via SMS or a mobile app (e.g. Google Authenticator). This code is short-lived and is extremely hard for a remote attacker to guess, thus vastly reducing the risk a leaked or easily guessed password presents.
The typical algorithm for 2FA is based on an IETF standard called the time-based one-time password (TOTP) algorithm, and it isn’t that hard to implement. Joel Franusic wrote a great post on implementing 2FA; modules like speakeasy make it even easier; and you can swap SMS with Google Authenticator or your own app if you prefer. If you don’t want to build 2FA support yourself, you can purchase two/multi-factor authentication services from vendors such as DuoSecurity, Auth0, Clef, Hypr and others.
If implementing 2FA still feels like too much work, you can also choose to offload your entire authentication process to an OAuth-based federated login. Many companies offer this today, including Facebook, Google, Twitter, GitHub and others. These bigger players tend to do authentication well and support 2FA, but you should consider what data you’re sharing with them in the process.
Tracking Known Vulnerabilities
Most of the code in a modern application was actually written by third parties, and pulled into your app as frameworks, modules and libraries. While using these components makes us much more productive, along with their functionality we also adopt their security flaws. To make things worse, some of these flaws are well-known vulnerabilities, making it easy for hackers to take advantage of them in an attack.
This is a real problem and happens on pretty much every platform. Do you develop in Java? In 2014, over 6% of Java modules downloaded from Maven had a known severe security issue, the typical Java applications containing 24 flaws. Are you coding in Node.js? Roughly 14% of npm packages carry a known vulnerability, and over 60% of dev shops find vulnerabilities in their code. 30% of Docker Hub containers include a high priority known security hole, and 60% of the top 100,000 websites use client-side libraries with known security gaps.
To find known security issues, take stock of your dependencies and match them against language-specific lists such as Snyk’s vulnerability DB for Node.js, rubysec for Ruby, victims-db for Python and OWASP’s Dependency Check for Java. Once found, you can fix most issues by upgrading the component in question, though that may be tricky for indirect dependencies.  
This process is still way too painful, which means most teams don’t do it. The Snyk team and I are hoping to change that by making it as easy as possible to find, fix and monitor known vulnerabilities in your dependencies. Snyk’s wizard will help you find and fix these issues through guided upgrades and patches, and adding Snyk’s test to your continuous integration and deployment (CI/CD) will help you stay secure as your code evolves.
Note that newly disclosed vulnerabilities usually impact old code – the one you’re running in production. This means you have to stay alert when new vulnerabilities are disclosed, so you can fix them before attackers can exploit them. You can do so by subscribing to vulnerability lists like US-CERT, OSVDB and NVD. Snyk’s monitor will proactively let you know about new disclosures relevant to your code, but only for Node.js for now – you can register to get updated when we expand.
Securing Yourself
In addition to making your application secure, you should make the contributors to that application secure – including you. Earlier this year we’ve seen attackers target mobile app developers with a malicious Xcode. The real target, however, wasn’t these developers, but rather the users of the apps they create. That you create. Securing your own work environment is a key part of keeping your apps secure, and your users from being compromised.
There’s no single step that will make you fully secure, but here are a few steps that can make a big impact:

Use 2FA on all the services related to the application, notably source control (e.g. GitHub), cloud platform (e.g. AWS), CI/CD, CDN, DNS provider and domain registrar. If an attacker compromises any one of those, they could modify or replace your entire application. I’d recommend using 2FA on all your personal services too.
Use a password manager (e.g. 1Password, LastPass) to ensure you have a separate and complex password for each service. Some of these services will get hacked, and passwords will leak. When that happens, don’t let the attackers access your other systems too.
Secure your workstation. Be careful what you download, lock your screen when you walk away, change default passwords on services you install, run antivirus software, etc. Malware on your machine can translate to malware in your applications.
Be very wary of phishing. Smart attackers use ‘spear phishing’ techniques to gain access to specific systems, and can trick even security savvy users. There are even phishing scams targeting users with 2FA. Be alert to phishy emails.
Don’t install things through curl <somewhere-on-the-web> | sudo bash, especially if the URL is on GitHub, meaning someone else controls it. Don’t do it on your machines, and definitely don’t do it in your CI/CD systems. Seriously.

Staying secure should be important to you personally, but it’s doubly important when you have privileged access to an application. Such access makes you a way to reach many more users, and therefore a more compelling target for bad actors.
A Culture of Security
Using HTTPS, enabling two-factor authentication and fixing known vulnerabilities are significant steps in building security at your core. As you implement them, remember that these are just a few steps in a longer journey.
The end goal is to embrace security as an aspect of quality, and accept we all share the responsibility of keeping ourselves – and our users – safe.",2015,Guy Podjarny,guypodjarny,2015-12-11T00:00:00+00:00,https://24ways.org/2015/upping-your-web-security-game/,code
72,Designing with Contrast,"When an appetite for aesthetics over usability becomes the bellwether of user interface design, it’s time to reconsider who we’re designing for.
Over the last few years, we have questioned the signifiers that gave obvious meaning to the function of interface elements. Strong textures, deep shadows, gradients — imitations of physical objects — were discarded. And many, rightfully so. Our audiences are now more comfortable with an experience that feels native to the technology, so we should respond in kind.
Yet not all of the changes have benefitted users. Our efforts to simplify brought with them a trend of ultra-minimalism where aesthetics have taken priority over legibility, accessibility and discoverability. The trend shows no sign of losing popularity — and it is harming our experience of digital content.

A thin veneer
We are in a race to create the most subdued, understated interface. Visual contrast is out. In its place: the thinnest weights of a typeface and white text on bright color backgrounds. Headlines, text, borders, backgrounds, icons, form controls and inputs: all grey.
While we can look back over the last decade and see minimalist trends emerging on the web, I think we can place a fair share of the responsibility for the recent shift in priorities on Apple. The release of iOS 7 ushered in a radical change to its user interface. It paired mobile interaction design to the simplicity and eloquence of Apple’s marketing and product design. It was a catalyst. We took what we saw, copied and consumed the aesthetics like pick-and-mix.
New technology compounds this trend. Computer monitors and mobile devices are available with screens of unprecedented resolutions. Ultra-light type and subtle hues, difficult to view on older screens, are more legible on these devices. It would be disingenuous to say that designers have always worked on machines representative of their audience’s circumstances, but the gap has never been as large as it is now. We are running the risk of designing VIP lounges where the cost of entry is a Mac with a Retina display.
Minimalist expectations
Like progressive enhancement in an age of JavaScript, many good and sensible accessibility practices are being overlooked or ignored. We’re driving unilateral design decisions that threaten accessibility. We’ve approached every problem with the same solution, grasping on to the integrity of beauty, focusing on expression over users’ needs and content. 
Someone once suggested to me that a client’s website should include two states. The first state would be the ideal experience, with low color contrast, light font weights and no differentiation between links and text. It would be the default. The second state would be presented in whatever way was necessary to meet accessibility standards. Users would have to opt out of the default state via a toggle if it wasn’t meeting their needs. A sort of first-class, upper deck cabin equivalent of graceful degradation. That this would divide the user base was irrelevant, as the aesthetics of the brand were absolute. 
It may seem like an unusual anecdote, but it isn’t uncommon to see this thinking in our industry. Again and again, we place the burden of responsibility to participate in a usable experience on others. We view accessibility and good design as mutually exclusive. Taking for granted what users will tolerate is usually the forte of monopolistic services, but increasingly we apply the same arrogance to our new products and services.

Imitation without representation
All of us are influenced in one way or another by one another’s work. We are consciously and unconsciously affected by the visual and audible activity around us. This is important and unavoidable. We do not produce work in a vacuum. We respond to technology and culture. We channel language and geography. We absorb the sights and sounds of film, television, news. To mimic and copy is part and parcel of creating something an audience of many can comprehend and respond to. Our clients often look first to their competitors’ products to understand their success.
However, problems arise when we focus on style without context; form without function; mimicry as method. Copied and reused without any of the ethos of the original, stripped of deliberate and informed decision-making, the so-called look and feel becomes nothing more than paint on an empty facade.
The typographic and color choices so in vogue today with our popular digital products and services have little in common with the brands they are meant to represent.

For want of good design, the message was lost
The question to ask is: does the interface truly reflect the product? Is it an accurate characterization of the brand and organizational values? Does the delivery of the content match the tone of voice?
The answer is: probably not. Because every organization, every app or service, is unique. Each with its own personality, its own values and wonderful quirks. Design is communication. We should do everything in our role as professionals to use design to give voice to the message. Our job is to clearly communicate the benefits of a service and unreservedly allow access to information and content. To do otherwise, by obscuring with fashionable styles and elusive information architecture, does a great disservice to the people who chose to engage with and trust our products.
We can achieve hierarchy and visual rhythm without resorting to extreme reduction. We can craft a beautiful experience with fine detail and curiosity while meeting fundamental standards of accessibility (and strive to meet many more).
Standards of excellence
It isn’t always comfortable to step back and objectively question our design choices. We get lost in the flow of our work, using patterns and preferences we’ve tried and tested before. That our decisions often seem like second nature is a gift of experience, but sometimes it prevents us from finding our blind spots.
I was first caught out by my own biases a few years ago, when designing an interface for the Bank of England. After deciding on the colors for the typography and interactive elements, I learned that the site had to meet AAA accessibility standards. My choices quickly fell apart. It was eye-opening. I had to start again with restrictions and use size, weight and placement instead to construct the visual hierarchy.
Even now, I make mistakes. On a recent project, I used large photographs on an organization’s website to promote their products. Knowing that our team had control over the art direction, I felt confident that we could compose the photographs to work with text overlays. Despite our best effort, the cropped images weren’t always consistent, undermining the text’s legibility. If I had the chance to do it again, I would separate the text and image.
So, what practical things can we consider to give our users the experience they deserve?
Put guidelines in place

Think about your brand values. Write down keywords and use them as a framework when choosing a typeface. Explore colors that convey the organization’s personality and emotional appeal.
Define a color palette that is web-ready and meets minimum accessibility standards. Note which colors are suitable for use with text. Only very dark hues of grey are consistently legible so keep them for non-essential text (for example, as placeholders in form inputs).
Find which background colors you can safely use with white text, and consider integrating contrast checks into your workflow.
Use roman and medium weights for body copy. Reserve lighter weights of a typeface for very large text. Thin fonts are usually the first to break down because of aliasing differences across platforms and screens.
Check that the size, leading and length of your type is always legible and readable. Define lower and upper limits. Small text is best left for captions and words in uppercase.
Avoid overlaying text on images unless it’s guaranteed to be legible. If it’s necessary to optimize space in the layout, give the text a container. Scrims aren’t always reliable: the text will inevitably overlap a part of the photograph without a contrasting ground.

Test your work

Review legibility and contrast on different devices. It’s just as important as testing the layout of a responsive website. If you have a local device lab, pay it a visit.
Find a computer monitor near a window when the sun is shining. Step outside the studio and try to read your content on a mobile device with different brightness levels. 
Ask your friends and family what they use at home and at work. It’s one way of making sure your feedback isn’t always coming from a closed loop.

Push your limits

You define what the user sees. If you’ve inherited brand guidelines, question them. If you don’t agree with the choices, make the case for why they should change.
Experiment with size, weight and color to find contrast. Objects with low contrast appear similar to one another and undermine the visual hierarchy. Weak relationships between figure and ground diminish visual interest. A balanced level of contrast removes ambiguity and creates focal points. It captures and holds our attention.
If you’re lost for inspiration, look to graphic design in print. We have a wealth of history, full of examples that excel in using contrast to establish visual hierarchy.
Embrace limitations. Use boundaries as an opportunity to explore possibilities.

More than just a facade
Designing with standards encourages legibility and helps to define a strong visual hierarchy. Design without exclusion (through neither negligence or intent) gets around discussions of demographics, speaks to a larger audience and makes good business sense. Following the latest trends not only weakens usability but also hinders a cohesive and distinctive brand.
Users will make means when they need to, by increasing browser font sizes or enabling system features for accessibility. But we can do our part to take as much of that burden off of the user and ask less of those who need it most.
In architecture, it isn’t buildings that mimic what is fashionable that stand the test of time. Nor do we admire buildings that tack on separate, poorly constructed extensions to meet a bare minimum of safety regulations. We admire architecture that offers well-considered, remarkable, usable spaces with universal access.
Perhaps we can take inspiration from these spaces. Let’s give our buildings a bold voice and make sure the doors are open to everyone.",2015,Mark Mitchell,markmitchell,2015-12-13T00:00:00+00:00,https://24ways.org/2015/designing-with-contrast/,design
