IE6 is known to have a host of CSS limitations, forcing web designers to come up with creative ways around the new CSS standards and Microsoft's poor integration of the new standards and their own proprietary way of doing things.

Early in my web design days, I found out about the wonderful psuedo :hover and the ability to make images transparent when hovered over, or originally transparent then full opacity when hovered over.

I had an issue with thickbox where it would show the image behind a flash video in FireFox. IE7 worked great. I ran across Sheriar Designs Blog posting a fix specifically for DHTML menus over a flash video. I figured I would give it a try and much to my surprise, the suggestion worked!
