CSS use :not ID with CLASS

Question

Does someone know how to use the CSS selector :not() as #some_id:not(.any_class_name)?

The code looks as if it is right, but it doesn't work. Is there another way without the not selector? I couldn't find anything on the Internet.

I am making a web application, which includes more than one page, but several pages have divs with id=some_id. I thought I had to add specific CSS by adding any_class_name one time using the above CSS code solve the problem, but it doesn't work.

I believe that you are reversing the selectors. You have some elements with the same class, but you want to filter out an element with an specific ID. In that case:

HTML:

<p class="someclass">hello</p> <!-- will be targeted by css below, thus green --> <p class="someclass" id="some-id">hi</p> <!-- will not be targeted by css below --> 

CSS:

.someclass:not(#some-id){ color: green; }  /* selects all elements with classname 'someclass',     but excludes the one that has also has an id of 'some-id' */ 

And as @secretSquirrel pointed out, note the browser compatibility: this selector is not supported by Internet Explorer 8 and older.
