MSN.com plays dirty with Opera

Opera yesterday revealed how MSN.com misforms their page on purpose to make it look like Opera is buggy.

As can be seen in the table above, 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 Opera 7 to move list elements 30 pixels to the left of its parent. That is, Opera 7 is explicitly instructed to move content off the side of its container thus creating the impression that there is something wrong with Opera 7.

A naughty move that definitely deserves a slap on the wrist...

Opera's view of this might be a bit biased. Not that I love Microsoft very much, but there seems to be a reasonable explanation to why they did this. And it's not to make Opera crash. See http://slashdot.org/comments.pl?sid=53008&cid=5247770
