: NOT SELECTOR CSS

Select all elements of a given class, except for a particular Id

Eg: If there is a class with the name “entry-content” for every page. And we are intending to give a particular CSS property for  “entry-content” except for home page with id “home”

then, the proper CSS selector is :not()selector

div.entry-content:not(#home) {
color:grey;
min-height:400px;
}
