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.

For how long has ALL the news links in the quick news side bar been all anti Microsoft. Until recently its hard to remember the last time other tech news has been posted that wasnt anti micrsoft... Like these for instanse... How long have they been there, Since Nov 5 Id guess..

Before the 2 new ones all 5 slots had links to anti microsoft news. And I must say that either they must be rather picky on the news they publish ( and theres been plently on non Microsoft news) or theyre just of the mind to bash MS all the time. Oh Asa when does defending something call for bashing on something else. I'd call unprovoked MS bashing "ATTACKING" and not defending. When ZDNet messed up then protest was defending. But when IE 5.5 came out basically saying it sucked is not defending. Using that kind of thinking is a kin to attack first ask questions later.
