:not()

Summary

The negation CSS pseudo-class, :not(X), is a functional notation taking a simple selector X as an argument. It matches an element that is not represented by the argument. X must not contain another negation selector.

The specificity of the :not pseudo-class is the specificity of its argument. The :not pseudo-class does not add to the selector specificity, unlike other pseudo-classes.

Notes:
  • Useless selectors can be written using this pseudo-class. E.g. :not(*) matching any element which is not any element will never be applied.
  • It is possible to rewrite other rules. E.g. foo:not(bar) will match the same element as the simple foo. Nevertheless the specificity of the first one is higher.
  • :not(foo){} will match anything that isn't foo, including html and body.

Syntax
