Rounded border

After several research.
Here is the thing that is needed to create rounded rectangle.
This works on FF and GC. Not on IE and dont know on others

-moz-border-radius: 20px 20px 20px 20px; background: none repeat scroll 0 0 #D8DEEF;
border-bottom-left-radius: 20px 20px;
border-bottom-right-radius: 20px 20px;
border-top-left-radius: 20px 20px;
border-top-right-radius: 20px 20px;
