Acid2 is a test page, written to help browser vendors ensure proper support for web standards in their products. Please take the Acid2 test!
Questions or concerns about the test or its documentation can be directed to acid2Feedback@webstandards.org.
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.
