title: Commenting a commented markup (Nested comments)
body: <p>How can I easily comment and uncomment a big chunk of HTML markup that that includes some comment?</p>
  
  <pre><code>&lt;body&gt;
  a lot of markups
   &lt;!-- comment --&gt;
  a lot of markups
   &lt;!-- comment --&gt;
  a lot of markups
  &lt;/body&gt;
  </code></pre>
  
  <p>Following do not work as desired (closing --> stops the comment section):</p>
  
  <pre><code>&lt;body&gt;
    &lt;!-- 
      a lot of markups
       &lt;!-- comment --&gt;
      a lot of markups
       &lt;!-- comment --&gt;
      a lot of markups
     --&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>Is there any alternative method?</p>
