Like probably many others who read this blog, I am a web design enthusiast, web standards advocate, and web designer by trade. I have been working with HTML since the early 2000s, and have enjoyed it ever since. Over the years, the web has evolved around me. I have watched it grow and adapt. And [...] Read more

The WHATWG now has a patent policy, the WHATCG. We will keep using the same mailing list, the same IRC channel, the same web sites, but now sometimes we will publish through the WHATCG as well for patent policy purposes per the W3C Community Final Specification Agreement.

This is the WHATWG Weekly. Some bad news for a change. It may turn out that the web platform will only work on little-endian devices, as [...] Read more

Modernizr is a JavaScript library that detects which HTML5 and CSS3 features your visitor’s browser supports. In detecting feature support, it allows developers to test for some of the new technologies and then provide fallbacks for browsers that do not support them. This is called feature detection and is much more efficient than browser sniffing.

Jonas Sicking proposed an API for decoding ArrayBuffer objects as strings, and encoding strings as ArrayBuffer objects. The thread also touched on a proposal mentioned here earlier, StringEncoding.

Apple's Safari team provided feedback to the Web Notifications Working Group. That group, incidentally, is looking for an active editor to address that and other feedback.
