A new beta of the W3C Markup Validator has been released, and the best news is that it supports the HTML 5 doctype, <!DOCTYPE html>.
This doctype will trigger standards mode in all current browsers, so you can start using it straight away*, secure in the knowledge that you can still validate your code.
* Note: See the first comment, below.
After two days of commotion regarding the Internet Explorer team’s decision to include a standards opt-in in the next version of their browser, Mozilla’s John Resig has noticed something rather important in an exchange on IE’s Chris Wilson’s blog; namely:
Internet Explorer 8 will support DOCTYPE switching for new DOCTYPEs (like HTML5).
For no particular reason other than idle curiosity, I made a demo of a broken neon sign, using CSS Animations (you’ll need Firefox 5, Safari or Chrome to see it). It doesn’t degrade well at the moment, the root cause of which is down to what I think is a bug in Firefox’s implementation — I’ll need to confirm that.
One quick learning from making this: it would be really useful to have CSS Mixins when using a lot of repetitive keyframes, as I do in this animation. The W3C seem to be quite against them, however.
