title: Make iframe automatically adjust height according to the contents without using scrollbar?
body: <p>For example:</p>
  
  <pre><code>&lt;iframe name="Stack" src="http://stackoverflow.com/" width="740"
          frameborder="0" scrolling="no" id="iframe"&gt; ...
  &lt;/iframe&gt;
  </code></pre>
  
  <p>I want it to be able to adjust its height according to the contents inside it, without using scroll.</p>
