title: Select body with an element with a specific id
body: <p>so i have a html page with a body and the following structure</p>
  
  <pre><code>&lt;body&gt;
      &lt;h1&gt;Hello&lt;/h1&gt;
      &lt;div&gt;
          &lt;div&gt;
              // editable area --&gt;
  
              &lt;div id="b"&gt;
                  &lt;h1&gt;Bye&lt;/h1&gt;
              &lt;/div&gt;
  
              // &lt;--
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>I want to style the <code>&lt;body&gt;</code> but can only access and edit the <code>&lt;div&gt;</code> with id "b" and add a custom css file. Since  the css file is used for more than one html files i can't just directly style the <code>&lt;body&gt;</code>.</p>
  
  <p>Is there a possibility to style a <code>&lt;body&gt;</code> with a specific child element (child of a child) with a specific id?  </p>
