The point is that you can't test on child > elements of the element the styles will be applied to, Yes, but I was asking whether one could test on element siblings of the element the styles will be applied to, for example. Thomas Lahn stated "there is just no descendant predicate/selector in CSS", but apparently I'm not aware one could do matching using element siblings, either. -- Stanimir

The W3C CSS working group has consistently rejected proposals for a parent selector (or various forms of it; it comes up every few months) for the following reasons: 1. Incremental rendering becomes messier (granted, :only-child and :only-of-type break this too) 2. DOM mutation performance goes to hell. The problem with styling columns is actually explained quite well by Ian Hickson here: <http://ln.hixie.ch/?start=1070385285&count=1>. In essence, you don't know what columns things are in until after you apply the CSS cascade, which is when things need to figure out their color. -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E.
