title: Embed a Youtube Channel into HTML with iFrame
body: <p>I'm trying to embed a Youtube channel into a HTML page. </p>
  
  <p>For example I take this channel address: <a href="http://www.youtube.com/aaaa" rel="noreferrer">http://www.youtube.com/aaaa</a></p>
  
  <p>I used this code: </p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;iframe src="http://www.youtube.com/aaaa"&gt;&lt;/iframe&gt; 
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The problem is that it doesn't work. I tried with another site, and it works. What can be the problem? </p>
