icrosoft’s Internet Explorer 9 and 10 browsers both pass the infamous Acid3 test thanks to changes by its authors.

Google employee Ian Hickson and Opera employee Håkon Wium Lie both announced changes to the Acid3 test on Saturday. The changes will allow more browsers to pass the test and focus on allowing the specs to change according to what’s best for the web. ”As the Web matures, we have made a concerted effort to improve the precision of Web technology specifications,” said Hickson in a Google+ post on Saturday.”We’re trying to simplify parts of the platform that still haven’t received broad use,” he added before explaining that the Acid3 test has been changed. “+Håkon Wium Lie and I are announcing that we have updated the Acid3 test by commenting out the parts of the test that might get changed in the specs.”

The Acid3 test is a popular way to check a web browser’s compliance with varios web standards. The test focuses mainly on the Document Object Model (DOM) and JavaScript features of the web. The test has long influenced browser vendors to make significant progress in their implementations of web standards. Microsoft’s Internet Explorer 8 browser only scored 20/100 on the test at the time of its release
