ACID2 is a standard CSS Test page maintained by The Web Standards groups. This is where Browser Vendor test their Browser CSS rendering capability. The first batch to pass this test is opera 9.1, icab (osx) & Firefox 3a.
The most popular browser vendor (Microsoft Internet Explorer) just pass this test for their IE8 Browser. I’m quite happy as Internet Explorer is a big liability to support by most web developer. Unfortunately The ACID2 Test pages FAILED W3C CSS2.1 Validations.
