Dose Your Browser With ACID 3
Most of the major browsers — Firefox 3, Safari, Opera and to a limited degree Internet Explorer 8 — pass or will pass the ACID 2 rendering test, which means it’s time for another test. ACID 3 picks up where ACID 2 leaves off and focuses on ECMAScript (which Javascript is derived from), DOM Level 3, Media Queries, and data: URLs.
The ACID 2 test was a test case designed by the Web Standards Project to give manufacturers a reference point and to help identify rendering flaws in browsers. ACID tests don’t necessarily prove anything, they simply create an extremely difficult test case with the idea that if a browser can render that page it should be able to handle almost any other page.
Where ACID 2 was designed to challenge a browser’s page rendering skills ACID 3 is aimed more at how a browser renders the DOM and handles Javascript.
The ACID 3 test is still a work in progress and is missing some features, but if you’d like to see how you favorite browser stacks up at the moment, head over and give it a try.
Fair warning though, the results wont be pretty. Opera fared the best in my informal tests (all on OS X), nabbing a 65 percent rating, with Firefox 3 at 63 percent and Safari 3 at 50 percent. Keep in mind that there are still sixteen or so more tests to add to ACID 3 so those scores may go down before they go up.
