CSS3

Opera have announced the first Alpha release of the next version of their browser. Codename Peregrine features version 2.2 of their Presto rendering engine, which boasts 100% Acid 3 compliance, a 30% speed boost on certain sites, and a number of new features for web developers.

As CSS enthusiasts it’s the latter we’re interested in, of course, and the notable CSS3 implementations are:

• Web fonts (OTF, TTF & SVG)
• HSLA & RGBA color values

There’s an overview of the new features on dev.opera.com.

Firefox 3 isn’t quite out yet, but already there are some exciting plans for CSS implementation in future versions.

FF3.1 should see all the selectors (test them here), @media queries, text-shadow, font-stretch, and downloadable web fonts with @font-face; FF4 should add calc() and attr() values, along with the Animation and Transitions modules proposed by the Webkit team.

You can see a list of other planned implementations on the Mozilla Wiki.
