There's actually a tricky little way of doing these with :nth-child() alone and without :not(), since the rule is that a child matches :nth-child(an+b) if there is a *nonnegative* value of n such that its index is an+b. This means that: :nth-child(n+5) matches children 5, 6, 7, ... :nth-child(2n+5) matches children 5, 7, 9, ... :nth-child(-n+7) matches children 1, 2, 3, 4, 5, 6, 7 :nth-child(-3n+8) matches children 2, 5, and 8 It's ugly, but it is possible. -David -- L.
