Why is ContentPlaceHolder content not displaying under IE9?

I'm working on a small ASP.NET project and just hit a wall. In a middle of a project, I started to test th开发者_Go百科e webpage on different browsers and detected that the content of the ContentPlaceHolder in MasterPage is not showing under IE9.

When I hit the compatibility view button, then it did displayed, but this is not a solution to my problem.

I do not have this problem in other browsers.

It's a css problem, not an asp.net problem. I've tried a few css things and it has something to do with this one

<div style="z-index: 3; position: absolute; padding-bottom: 20px; background-color: white; padding-left: 20px; width: 760px; bottom: 10px; padding-right: 20px; padding-top: 20px; left: 2px;">

for instance delete the width and see the result... My advise is to use relative position and float:left; to position your form. I'm not to confident with absolute positioning to present you a solution to this problem

This should solve your problem

 #containerDiv{clear:both;float:left;display:block;}
