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.

That's interesting: Whenever there is an article about MS in here, you get some 100+ responses.

But now lets face it. Most people compare IE5.x to Navigator 4.x; but that is unfair; That is like comparing Win95 to Win98. You must compare two similar versions. And from this point of view, NN4.x beats IE4.x For IE5 I must say, MS did a good job, but I don't compare it with NN4.x or Gecko, cause the NN4. Is an “old” version and Gecko is Alpha/Beta (whatever).

All I can say for now is, that the people working on Mozilla should take care of the following: - Companies must have the possibilities to change to look and fell of NN5 to match their needs without any programming knowledge. XUL is very good! Every company that can add their logos and buttons and whatever will distribute NN5. Thats what we need! - NN5 must be faster and easier to handle then IE5, so users are willing to switch back to NN. Plus it must be able to display anything, IE does. (OK, that's hard, but lets say most of it) - -And finally: AOL must stop distributing IEx with their Software.

OK, so far for this.

Take care
