Internet Explorer 8 (download) represents a leap forward in support for web standards. We believe that IE8 has the first complete implementation of CSS 2.1 in the industry and it is fully compliant with the current CSS 2.1 test suite. The IE Team is submitting 196 new test cases to the CSS 2.1 Working Group for inclusion into the CSS 2.1 test suite. These cases were developed since IE8 RC. This brings Microsoft’s contribution to the CSS 2.1 Test Suite to 7201 tests. IE8 passes all of these tests today as well as the rest of the tests in the current official CSS 2.1 test suite. We’re working closely with the CSS working group to include the new tests in the official test suite. For now, these tests are available at the Windows Internet Explorer Testing Center, said Jason Upton.
