18 Grunt for People Who Think Things Like Grunt are Weird and Hard Front-end developers are often told to do certain things: Work in as small chunks of CSS and JavaScript as makes sense to you, then concatenate them together for the production website. Compress your CSS and minify your JavaScript to make their file sizes as small as possible for your production website. Optimize your images to reduce their file size without affecting quality. Use Sass for CSS authoring because of all the useful abstraction it allows. That’s not a comprehensive list of course, but those are the kind of things we need to do. You might call them tasks. I bet you’ve heard of Grunt. Well, Grunt is a task runner. Grunt can do all of those things for you. Once you’ve got it set up, which isn’t particularly difficult, those things can happen automatically without you having to think about them again. But let’s face it: Grunt is one of those fancy newfangled things that all the cool kids seem to be using but at first glance feels strange and intimidating. I hear you. This article is for you. Let’s nip some misconceptions in the bud right away Perhaps you’ve heard of Grunt, but haven’t done anything with it. I’m sure that applies to many of you. Maybe one of the following hang-ups applies to you. I don’t need the things Grunt does You probably do, actually. Check out that list up top. Those things aren’t nice-to-haves. They are pretty vital parts of website development these days. If you already do all of them, that’s awesome. Perhaps you use a variety of different tools to accomplish them. Grunt can help bring them under one roof, so to speak. If you don’t already do all of them, you probably should and Grunt can help. Then, once you are doing those, you can keep using Grunt to do more for you, which will basically make you better at doing your job. Grunt runs on Node.js — I don’t know Node You don’t have to know Node. Just like you don’t have to know Ruby to use Sass. Or PHP to use WordPress. Or C++ to use Microsoft Word. I have other ways to do the things Grunt could do for me Are the… 2013 Chris Coyier chriscoyier 2013-12-11T00:00:00+00:00 https://24ways.org/2013/grunt-is-not-weird-and-hard/ code
20 Make Your Browser Dance It was a crisp winter’s evening when I pulled up alongside the pier. I stepped out of my car and the bitterly cold sea air hit my face. I walked around to the boot, opened it and heaved out a heavy flight case. I slammed the boot shut, locked the car and started walking towards the venue. This was it. My first gig. I thought about all those weeks of preparation: editing video clips, creating 3-D objects, making coloured patterns, then importing them all into software and configuring effects to change as the music did; targeting frequency, beat, velocity, modifying size, colour, starting point; creating playlists of these… and working out ways to mix them as the music played. This was it. This was me VJing. This was all a lifetime (well a decade!) ago. When I started web designing, VJing took a back seat. I was more interested in interactive layouts, semantic accessible HTML, learning all the IE bugs and mastering the quirks that CSS has to offer. More recently, I have been excited by background gradients, 3-D transforms, the @keyframe directive, as well as new APIs such as getUserMedia, indexedDB, the Web Audio API But wait, have I just come full circle? Could it be possible, with these wonderful new things in technologies I am already familiar with, that I could VJ again, right here, in a browser? Well, there’s only one thing to do: let’s try it! Let’s take to the dance floor Over the past couple of years working in The Lab I have learned to take a much more iterative approach to projects than before. One of my new favourite methods of working is to create a proof of concept to make sure my theory is feasible, before going on to create a full-blown product. So let’s take the same approach here. The main VJing functionality I want to recreate is manipulating visuals in relation to sound. So for my POC I need to create a visual, with parameters that can be changed, then get some sound and see if I can analyse that sound to detect some data, which I can then use to manipulate the visual parameters. Easy, … 2013 Ruth John ruthjohn 2013-12-02T00:00:00+00:00 https://24ways.org/2013/make-your-browser-dance/ code
23 Animating Vectors with SVG It is almost 2014 and fifteen years ago the W3C started to develop a web-based scalable vector graphics (SVG) format. As web technologies go, this one is pretty old and well entrenched. See the Pen yJflC by Drew McLellan (@drewm) on CodePen Embed not working on your device? Try direct. Unlike rasterized images, SVG files will stay crisp and sharp at any resolution. With high-DPI phones, tablets and monitors, all those rasterized icons are starting to look a bit old and blocky. There are several options to get simpler, decorative pieces to render smoothly and respond to various device widths, shapes and sizes. Symbol fonts are one option; the other is SVG. I’m a big fan of SVG. SVG is an XML format, which means it is possible to write by hand or to script. The most common way to create an SVG file is through the use of various drawing applications like Illustrator, Inkscape or Sketch. All of them open and save the SVG format. But, if SVG is so great, why doesn’t it get more attention? The simple answer is that for a long time it wasn’t well supported, so no one touched the technology. SVG’s adoption has always been hampered by browser support, but that’s not the case any more. Every modern browser (at least three versions back) supports SVG. Even IE9. Although the browsers support SVG, it is implemented in many different ways. SVG in HTML Some browsers allow you to embed SVG right in the HTML: the <svg> element. Treating SVG as a first-class citizen works — sometimes. Another way to embed SVG is via the <img> element; using the src attribute, you can refer to an SVG file. Again, this only works sometimes and leaves you in a tight space if you need to have a fallback for older browsers. The most common solution is to use the <object> element, with the data attribute referencing the SVG file. When a browser does not support this, it falls back to the content inside the <object>. This could be a rasterized fallback <img>. This method gets you the best of both worlds: a nice vector image with an alternati… 2013 Brian Suda briansuda 2013-12-07T00:00:00+00:00 https://24ways.org/2013/animating-vectors-with-svg/
