Otherwise, what was the point of adding the :enabled and :disabled pseudo classes when you could do that with attribute selectors and the disabled attribute. What difference do you think there is between pseudoclasses and attribute selectors? Other than the fact that they refer to different things, they're fairly similar. :enabled and :disabled were presumably introduced for parsimony with the other input-state-based pseudoclasses. It's also easier to write them than [disabled] and :not([disabled]) (plus, I don't think :not() existed at the time :enabled was first created?). ~TJ
