Controlling it through CSS definitely seems to be very high-level.  To me
at least it feels like it requires a lot more answering of "how" since it
deals with identifying elements by way of rules/selection in order to
differentially identify other elements by way of rules/selection.  At the
end of the day you have to identify particular elements as different
somehow and explain how that would work.  It seems better to start there at
a reasonably low level and just keep in mind that it might be a future aim
to move control of this sort of thing fully to CSS.  Since CSS matching
kind of conceptually happens on 'not exactly the DOM tree' (pseudo
elements, for example) it seems kind of similar to me and it might be worth
figuring that out before attempting another high-level feature which could
make answering 'what's the path up' all that much harder.
