Document for CSS differences between IE and FF

Is there a layman document out there describing what are the differences in rendering CSS styles between IE and FF (or IE and the rest of the world) that is more straigh开发者_StackOverflowtforward than quirksmode.org, which is very specification-centric? for example, I just wasted a lot of time figuring out one difference in rendering tables with different width styles between table rows and the table itself, which I couldn't find quickly in the quirksmode table...

Here's a decent (and non-headache-inducing) list of some issues with Internet Explorer, mostly IE 6.

Someone might be able to do me one better though.

I don't know about a reference list... but the one issue which comes to mind for me (and it's not quite CSS) is the placement of your <!DOCTYPE> declaration.

IE will not pay any attention to your <!DOCTYPE> declaration if it is not the very, very, very first thing on the first line of the file. If you put your <!DOCTYPE> declaration anywhere else IE starts to do whatever it wants with the rendering of your document.

I've seen even the most seasoned professionals bugger this up; they think "Oh, hey, I'm using a DOCTYPE; everything must be good now, right?" WRONG.
