title: CSS :not selector doesn't work
body: <p>This is probably a really stupid question, but I can't get the :not selector to work in css. I want to color all text in my page unless it has a class called "nocolor". Here's the code, I don't see the problem:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>*:not(.nocolor) {
      color: #f00;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;h2&gt;Hello&lt;/h2&gt;
  &lt;h2 class="nocolor"&gt;Hello&lt;/h2&gt;</code></pre>
  </div>
  </div>
  </p>
