IE5.5: First Look

Friday December 3rd, 1999

I've done some preliminary CSS testing of IE5.5 (available through Specifically I ran IE 5.5 through the battery of David Baron's CSS tests, and found some interesting results. IE 5.5's CSS support has undergone very little change from 5.0, and some regressions were noticable. IE 5.5 seems to pass test 5.3 (CSS2 Universal Selector) that IE 5.0 did not, but it fails two tests in section 6.4.4 (Parsing Test 4 and Test 5) that IE 5.0 apparently passed. There was one other that *may* have passed (9.1.2) where 5.0 failed, and one test in 10.7 *may* have failed where 5.0 passed, but I can't determine these for a certainty. Finally, IE 5.5 still does not pass the Box Acid Test.

According to MS's "What's New in Internet Explorer 5.5" page, IE 5.5 handles more "CSS styles" such as first-letter and first-line, but they don't go into any more detail.

From these results, I'm wondering if MS is giving up completely on significant advances in the CSS support in their current rendering engine. IE on the Mac is supposedly being developed to utilize a new rendering engine, codename "Tasman". Maybe Microsoft is planning something similar for their 6.0 Windows version.

In any event it does not look like the next version of IE will have significant CSS improvements as many hoped and expected.

You all are hip to the tactics of trolls. Don't let 'em get to you. We come here because we want mozilla to succeed. We post here because we want others to want mozilla to succeed. We have the best of intentions and we are on the side of good. There is nothing wrong with defending something you believe in, even if it means being a little fanatic at times. I love a particular football team and have no problem supporting them, through a bad quarter, a bad game, and even a bad season, because I have confidence in their program and in their people and I know that soon it will pay back my investment. I believe in mozilla. I will defend it when I feel that my defense will be productive. I will support it even if it is moving toward the goal slower than I would wish because I believe in the philosophy and I think it is a solid program. I am through responding to the trolls and will save any more words for situations in which they will be productive. I encourage others to do the same. And don't forget BugDay. It's every Tuesday on IRC at #mozillazine. Come check it out. Be a part of the solution. :)
