title: How to wrap <noscript> tag to hide content when javascript disable
body: <p>Let's say, I have HTML code like this:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  &lt;head&gt;
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
  &lt;title&gt;Untitled Document&lt;/title&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  This is content.
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And I want to add a <code>&lt;noscript&gt;</code> tag there. Which means, if the JavaScript disabled, it will show as a blank page.</p>
  
  <p>And only when JavaScript is disabled, it will show "This is content text". </p>
  
  <p>Please give me some examples to achieve. Thanks.</p>
