title: CSS use :not ID with CLASS
body: <p>Does someone know how to use the CSS selector <code>:not()</code> as <code>#some_id:not(.any_class_name)</code>? </p>
  
  <p>The code looks as if it is right, but it doesn't work. Is there another way  without the <code>not</code> selector? I couldn't find anything on the Internet.</p>
  
  <p>I am making a web application, which includes more than one page, but several pages have divs with <code>id=some_id</code>. I thought I had to add specific CSS by adding <code>any_class_name</code> one time using the above CSS code solve the problem, but it doesn't work.</p>
