<div id="a"> has z-index:1, <div id="b"> has z-index:2 and transparent as background color. "b" has right text alignment and contains one image. Shouldn't text in "a", visible through "b", be selectable if there is nothing directly over in "b"? I've purposefully stacked a transparent .gif over divs before to achieve just that - was I wasting my time? Causing me pause before moving on to "C".
