title: Multiple descendant children selector with css
body: <p>Check this code below:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.aaa :not(.bbb) .ccc {
    font-size: 20px;
    color: #FF0000;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="aaa"&gt;
      &lt;div&gt;
          &lt;div&gt;
              &lt;div class="bbb"&gt;
                  &lt;div&gt;
                      &lt;div&gt;
                          &lt;div class="ccc"&gt;AQUI&lt;/div&gt;
                      &lt;/div&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I want to match all <code>.ccc</code> element that are children of <code>.aaa</code> but are not children of <code>.bbb</code>. It means that the code above should NOT make the AQUI word be RED, but it gets RED anyway. What am I doing wrong?</p>
