Web Standards Project releases Acid3

Three years after the Acid2 test was released, the WaSP has developed Acid3. What’s Acid? It’s a reference test designed to help browser developers determine whether they are complying with W3C specifications, and how well they handle invalid code.

Acid1 and Acid2 tested for compliance with CSS 1 and CSS 2 specifications. Acid3 also tests for support of DOM Scripting / ECMAScript, SVG and webfonts.

Safari 3 and Opera 9 pass the Acid2 test, as does the beta version of Firefox 3. Version 8 of Internet Explorer will also pass the Acid2 test.

Here’s how today’s leading browsers handle Acid3 (check out the reference image). Each image links to a larger screenshot.

Opera 9.26

Version 8 of Internet Explorer will also pass the Acid2 test.

Not unless the IE team has announced that the Acid2 URL will be hardcoded to use the IE8 renderer instead of its default mode of IE7 rendering.

Guess what Carina: they did just that.

I just came back here to give a mea culpa. Though of course, today’s announcement is much better than hardcoding special behavior for Acid2. They’ve decided to set a sensible default, period. It’s almost strange to see MS making a decision that doesn’t make our lives harder. Now we’ll see what’s in store for XHTML. Fingers crossed!

Yeah, I’m doing a happy dance about this announcement myself :-).
