CTO of Opera Software and father of CSS, Håkon Wium Lie, has publicly announced a challenge to Microsoft through a test suit known as Acid2. Lie and the Web Standards Project are developing a test page that uses features such as fixed positioning of elements. The purpose of this effort is to encourage Microsoft to implement CSS 2 support in IE7.

It’s no surprise the article has hit the blogosphere streets at Slashdot and ZDNet. As a member of the Web Standards Project, I’m eager to see what comes of this.

Uber blogger and Microsoft employee, Robert Scoble, speaks up about Acid2. His initially posted this entry and then followed up with another. Click on Comment (this is a usability issue as it implies you’re posting a comment rather than there are multiple comments to read) at the end of the post to read the interesting responses especially from setmajer.
