body: <p>Why i can't hide this content from an iframe:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
  &lt;meta charset="utf-8"&gt;
  &lt;title&gt;contents demo&lt;/title&gt;
  &lt;script src="https://code.jquery.com/jquery-1.10.2.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;iframe src="//api.jquery.com/" width="80%" height="600" id="frameDemo"&gt;&lt;/iframe&gt;
  
  &lt;script&gt;
  $('#frameDemo').contents().find('#logo-events').hide();
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
