C S S, Is That a Good Idea?

Utilities are far more likely to give you consistency than customs seses will, because they are built on a system. We have both utilities and patterns that are commonly used - like an ovel or buttons. For us it works to have to you to use both approaches. But i think the approach that you'are talking about of nocrating abstractions using c s s when it makes sense is definitely the most practical way to go.
