Re: Why is there != attribute selector in CSS?

Agreed. It makes sense. Seems unnecessarily redundant.

Because :not() can accept elements, id's, or classes. So there's not much
that it's lacking.

Also while '!' is primarily used and known as not/opposite in programming,
in CSS it means the opposite.
For instance in overriding superior styles, !important does not mean not
important, but the most important.

Therefore, the '!' notation must not be introduced or used in CSS, to mean
not/opposite, as it already has its own meaning.
