Description

This pseudo-class is also known as the negation pseudo-class. The argument it takes can be any simple selector, but it can’t contain either the negation pseudo-class or a pseudo-element. This pseudo-class matches elements that aren’t matched by the specified selector.

For example, the selector, input:not([type="submit"]), matches all input elements, except input elements with a type value of "submit"—that is, HTML submit buttons.
