Acid2 Browser Test
Acid2 is a test page, written to help browser vendors ensure proper support for web standards in their products. Please take the Acid2 test!
If you’d like more in-depth information about the Acid2 test, we’ve provided a detailed technical guide that explains how the test works.
Note: Some 827 people (rough estimate, contents may have settled during shipping) have written to point out that the CSS used in the test is invalid. This is deliberate, as a means of exposing the ability of user agents to handle invalid CSS properly.
Note: When taking the test, you should use the default settings of the browser you are testing. Changing the zoom level, minimum font size, applying a fit-to-width algorithm, or making other changes may alter the rendition of the Acid2 page without this constituting a failure in compliance.

What’s the best test for Acid3?
By Kimberly Blessing | January 16th, 2008
Now that all the major browsers (and many minor ones) have pledged support for Acid2, Ian Hickson has moved on to preparing Acid3 — and you can help!
Perhaps you expected this announcement, given the news that IE8 passes Acid2. Or maybe it already seems like old news, if you caught the recent Slashdot post. In either case, the news is true — Acid3 will be coming soon!
Whereas Acid2 tested static HTML and CSS, Acid3 will focus on ECMAScript and DOM — the dynamic side of the Web. While it will include a few rendering tests to make things look interesting, the core of the test will be 100 scripting subtests.
And that is where you can contribute! Ian has compiled 84 of the 100 scripts but is seeking 16 additional tests. If you’re up to the challenge, read the criteria, create your test, and submit it — within the next five days!
As with Acid2, the Web Standards Project will play host to Acid3… so stay tuned for the final test, and the play-by-play on the browsers’ progress!
