David Storey, Chief Web Opener at Opera, has announced on his blog that the latest internal builds of the Opera browser have advanced CSS3 selectors support.
Some of the new selectors are already enabled in the builds, while others have been implemented but not yet enabled due to technical reasons. All are hoped to be available in a future release version.
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.
