The W3C has published the results of a HTML5 conformance test on the latest builds of the five most popular browsers and found that the latest platform preview of Internet Explorer 9 delivers the best results. The test affirms Microsoft's promise that IE9 will put a huge focus on standards, compliance and compatibility.
The latest platform preview of IE9 managed a perfect score on five of the tests, ranked top with a score of 89.55 per cent on the sixth and came in third on the final metric. The latest beta version of Chrome 7 came in second, followed by Firefox 4 beta 6 and Opera 11 alpha, with Safari 5.02 bringing up the rear of the pack.
Obviously these tests only represent a small slice of the HTML5 standard, which in turn only accounts for a fraction of all of the content on the web. Nonetheless, it's reassuring to see Microsoft's commitment to interoperability and conformity in practice, even at this early stage. If nothing else, it shows that the software-giant is genuinely trying - and largely succeeding - in creating a competent, competitive browser.
