Okay, this will mean nothing to most people out there, but to web developers, particularly those who use standards-based design to maximize compatibility with different browsers, this is monumental.
An internal build of Internet Explorer 8 has passed Acid2.
The Acid2 test was released in April 2005 to test a number of pieces of the HTML and CSS standards that, at the time, no modern browser handled according to spec. The purpose of the test was to prod browser developers into improving their products, and to do so consistently, so that developers would have more tools available for cross-browser sites.
At the time, Microsoft dismissed its its importance entirely. Even though they were working on rendering improvements for IE7, they stated that Acid2 was not one of their goals. Meanwhile Opera and Firefox were both in the wrong phase of their development cycles to make sweeping changes, so Safari jumped on it and became the first browser to pass. (Every once in a while I see someone say Opera was the first, and I have to wonder where they were.) Opera followed with version 9, and the Firefox 3 betas pass it as well.
With Gecko (Firefox), WebKit (Safari), Opera and IE accounting for the four biggest web browsers and the most popular minor browsers (Flock, Camino, Shiira, etc., plus IE shells like Maxthon), this shows unprecedented convergence among clients. It will be much easier to develop a cross-browser website that runs on IE8, Firefox 3, Opera 9+ and Safari 3+.
There are, of course, many aspects of the specs that aren’t covered by Acid2. And there are emerging standards like HTML5 and CSS3. And there are plenty of other bugs, quirks, and extensions among various browsers (IE’s bizarre concept of having layout, for instance, trips up all kinds of weird issues). And then there’s waiting for IE8 to be released, and moving people up from IE7, not to mention all the people we still have to move up from IE6. Full benefit is probably at least 3 or 4 years away. *sigh*
