Microsoft’s latest version of Internet Explorer 9 is the best browser at conforming to HTML5 standards, according to figures released by the World Wide Web Consortium.

Using an as-yet unreleased version of the browser – Platform Preview 6 – IE surprised many by achieving better standards compliance scores than Safari, Firefox Chrome and Opera in a test that checked seven elements of the standard.
Explorer was 100% compliant in five tests – for atrributes, audio, foreigncontent, video and xhtml5 – while it scored 83% for getElementsByClassName and 90% for canvas tag testing.
However, the W3C pointed out that the results were by no means an endorsement of Microsoft’s browser and that the test procedure remained a work on progress.
“The HTML5 Test suite is still being developed,” the work group said. “The number of tests and the results on these tests will change. It is inappropriate to cite those results as other than work in progress and unstable.”
