css - IE7 Absolute element appearing behind relative one

Question

I know there is the bug where absolute elements appear above relative ones. However I am getting the reverse of this issue.

The z-index on the "bottom" element is 1 and has a position:relative assigned. The top element has absolute positioning and a z-index of 99.

This works fine in Firefox, Webkit based browsers and IE8. Any ideas about why this could be happening?

Answer 1

In Internet Explorer positioned elements generate a new stacking context, starting with a z-index value of 0. Therefore z-index doesn't work correctly.
