Now, after Safari, iCab, Konqueror & Opera 9 beta, it’s Firefox’ turn to comply with the ACID2 test. David Baron has built a special development version of Firefox that fixes some rendering issues that kept it from complying before. You can see the screenshot of ACID2 in action on his Flickr account.
Now, why is seeing a smily face a good thing? Well, hopefully, this will bring about full cross-browser handling of CSS. And hopefully the times of hacking around for browser differences is coming to an end. IE7 fixes a lot of CSS-bugs, but apparently is not fully compliant to all CSS-standards. So the questions remaining: When will it be incorporated in the regular Firefox? When will IE(7) comply?
