CSS use :not ID with CLASS

css, css-selectors

Solution

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.

Problem

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.
