It can cause problems, but not if you do it right. For instance, if you
use the star html hack in your main style sheet to feed a rule to IE 6
and lower, and IE 7 doesn't need the different rule, then there is no
harm in including it in your style sheet. You're only hacking dead
browsers at this point, so you're safe. (I suppose you could argue that
they could add back support for star html to IE 8, but even in that
extremely unlikely case, you'd have to go back to all your sites anyway
to fix other things if the IE team was that foolish, so it wouldn't hurt
to have this one extra hack to fix.)
If, on the other hand, you need that different rule to be read by IE 7
in addition to IE 6 and lower (which I find is usually the case -- IE 7
needs almost as many hacks as IE 6), then you're probably best off just
feeding that rule to all versions of IE via a separate sheet hidden from
other browsers through conditional comments.
