Earlier this month a post appeared on the whatwg discussion list, proposing a pie-in-the-sky-ish modification to (presumably HTTP, or maybe SPDY) standards: 'let browsers report device capabilities in a request header'. The proposal touched off a huge, passionate discussion, whose end result was: the new W3C Responsive Images Community Group.

Site navigation with an accordion widget? Yes, it's efficient, and jQuery can do it easily; but can you do it with CSS3 alone? Yes, of course; and here's how, with full code.

Isolated testing lets you quickly find and correct particular problems, but does a poor job locating site-wide and integration errors. For end-to-end functionality testing, Zombie.js makes quick checks easy -- and, besides, lets Daniel Mohl use his very own ExpectThat project, a CoffeeScript library for writing expressive, self-documenting unit tests. In this post Daniel explains exactly how to use ExpectThat with Zombie.js, with a simple code example.

With regards to visual information from sporting events, Luis Sobrecueva realized something cool: most games are played on a grass surface; so items moving on the surface (ball, people) can be detected as less-green fields. So he tossed together a cool Canvas with some sweet JavaScript that looks for the ungreen, and stitches the ungreen together...

Recently I discovered the annotated and hyperlinked ES5 refererence, which is pretty cool in itself. But it's still massive enough that a dynamic interface would improve readability considerably, and a new project to dynam-ify the document might take a big step in that direction. Meanwhile, Chrome just made some new ECMAScript features available in its dev channel, which anyone interested in ECMAScript.next might want to check out.

There's a great video on YouTube detailing an Easter Egg in the score for the movie Inception. Basically Inception is about dreams and the slowing down of time. Likewise the score is based on the slowing down of music that is played inside the plot of the movie. Pretty cool. But Terence Ryan added even more cool by using this concept to show off the Audio capabilities in HTML5.

Robert Nyman shares his thoughts on the CSS vendor prefixing problem and possible solutions. First, blaming one group in particular (developers, CSS WG, browser manufacturers) makes little sense -- and in any case the blame game is never very productive. Second, there are two possible solutions: evangelizing web developers, to make sure they use all vendor prefixes in their code (not just -webkit); or implementing the -webkit prefix in every browser, at least for a few prominently used features.

Java developers don't always appreciate the pressures web developers face, and web developers (stereotypically) don't press their coding skills too hard. Matt Raible addressed both of these points in two presentations he gave at Jfokus 2012 -- one slideshow 'Comparing JVM Frameworks', another treating 'HTML5 with Play Scala, CoffeeScript, and Jade'.

Today the W3C advanced the spec for CSS Backgrounds and Borders Module Level 3 to Last Call status. This means that the WG is happy with the standard, and officially invites all web developers to test and critique the specification (though in reality the back-and-forth has been going on for some time).

Recently Microsoft made available videos of several sessions at their latest HTML5 Web Camp in Silicon Valley. The series covers basics of HTML5 and CSS3, plus in-depth dives into the most popular features (Canvas, SVG, audio, and video). Even if you're already somewhat familiar with the standards, the videos gel nicely together. If you're just starting to try HTML5, these videos will serve as a free substitute for a full-fledged web camp.

Quite a few web devs reeled and fired back against a recent CSS Working Group meeting that seriously considered admitting WebKit prefixes as part of the CSS spec. But how can you avoid accidentally using a WebKit-only prefix, while still implementing experimental but standard CSS3 for WebKit browsers? And more importantly, how can you make sure that awesome but non-standard CSS features eventually become part of the spec?
