Question

Is p.error better or worse than .error?

I have read that element-specific selectors are bad and should be used only if really needed but noone seems to know why. I mean I do understand that .error is better for code reuse, but is there somekinda specific reason why I shouldn’t address class with element always?

.error is more efficient than p.error .
