The IE team has announced that they’ve submitted an additional 2524 more test cases to the W3C for inclusion into the CSS 2.1 test suite. This brings the test suite much closer to the necessary breadth needed to ensure that web sites will interoperate. These tests are available on the IE Development Forum until they are fully reviewed by the working group and accepted into the official test suite.
This brings Microsoft’s contribution in this suite to 3221 test cases and the entire W3C CSS 2.1 test suite to 3708 test cases. We, the IE team, will continue to work closely with the CSS working group on these tests and listen to any feedback you provide.
In addition to the CSS 2.1 standard, IE8 is supporting the new Accessibility Rich Internet Applications (WAI - ARIA) draft standard in development by the W3C. It provides a way to create web sites that are accessible to people that need Assistive Technologies to help them live and work.
