In general, z-index only applies to positioned elements as already noted. http://www.w3.org/TR/CSS21/visuren.html#propdef-z-index However, transformed() elements establish their own stacking context, and z-index _should_ apply even if the element is not positioned. http://www.w3.org/TR/css3-2d-transforms/#introduction > Any value other than ‘none’ for the transform results in the creation of both > a stacking context and a containing block.

The text does not yet mention z-index… it was agreed within the CSS WG, however. http://lists.w3.org/Archives/Public/www-style/2011Apr/thread.html#msg116 BTW - a positive z-index will move your element higher in the stacking order, if you want it below (under), try a negative z-index.
