Hmm. Opacity creates a stacking context in Gecko, as I explained in my previous mail. Firefox 2.0 puts the blue box behind the yellow box. Gecko 1.9 (nightly builds, Fx 3 beta 1) puts the blue box in front, just as Safari 2 and 3. Which one is correct ? The yellow box has a z-index of '1', higher than the implicit z- index of the blue box (according to D.Hyatt [1], opacity gives a z- index of '0'). Shouldn't the yellow box be on top ? This is what happens if the blue box had 'position:relative' and 'z- index:0' instead of using 'opacity'. (position relative with auto z- index being analogous to opacity).
