CSS rendering on IE help needed

Question

I am pulling my hair trying to find a fix for this problem. If you go to this site you will see that (under IE) the slider and the menu on the top is broken. Works fine under all modern browsers.

Any idea how to fix this? Thanks.

Edit: Want to add that the original site design works fine under IE. I did a massive amount of editing under the hood and somewhere along the line this one was broken that I can't seem to find a fix for. Since I did a lot of customization, I think it seems unfair to ask the original author for a fix (and he is not very responsive either).

Answer 1

No fix but a lead: the issue with the menu bar is one of IE's mysterious float positioning bugs, as can be demonstrated by putting <div style="clear: both">xxx</div> after the navbar ul. (Note that it won't work if the div has no content!)

stuff about box model deleted: as David Dorward mentions this is caused by quirks mode, and moving the style down past the doctype causes the slider to behave sensibly.

Answer 2

The document invalid. In particular, there is a <style> element before the Doctype. This triggers Quirks mode and causes browsers to become very inconsistent (e.g. IE emulates a log of bugs from IE 5.5).

Always work in standards mode and perform basic automated QA.

Answer 3

I can't check it for you, since I've not got access to IE right now, but I've often found that adding position:relative to misbehaving elements is something of an IE magic bullet.
