z-index bug in IE 7

This is going to be a short, but sweet blog post that I thought everyone should know. Have you ever run into a problem where IE7 just won't listen to a style where you are trying to change the z-index of an image or list item?
Well try this quick fix.

If you are targeting an element like the following example:

#page ul li.button {

And you are not getting the results you expect in IE7 try adding the position:relative; to the element. 9 times out of 10 it seems to resolve my z-index problems.
