Why doesn't MSN work with Opera?
... Opera7 receives a style sheet which is very different from the Microsoft and Netscape browsers. Looking inside the style sheet sent to Opera7 we find this fragment:ul { margin: -2px 0px 0px -30px; }The culprit is in the "-30px" value set on the margin property. This value instructs Opera7 to move list elements 30 pixels to the left of its parent. That is, Opera7 is explicitly instructed to move content off the side of its container thus creating the impression that there is something wrong with Opera7."
