top:expression(body.scrollTop + 4 + "px");
I'm unfamiliar with CSS expressions. Can someone point me to a source that has been used by list members. Also doesn't this contradict the effort of separation of code and content?
CSS Expressions arn't standard :)
...They're a propriety "extension" brought in by Microsoft, they did submit it for proposal, but it was declined, it is a good idea (in paper) though
But since IE is the only browser that supports it, its not worth using unless you need the functionality provided by CSS2.1, such as max-width, min-width, max-height, etc... that Trident IV doesn't support. (Trident IV is the name of the current "MSHTML" rendering engine)
...But best to keep "extensions" in an IE-only stylesheet hidden by conditional comments and the like, thus keeping the rest of your code valid
