title: How to change height of iframe based on dynamic conent within the iframe?
body: <p>I have an iframe that has dynamic content.  If the answers specific questions, additional information displays (hidden div becomes visible).  I'd like the height of the iframe to expand.  I know this question has been asked on here multiple times, but it seems like it is typically when a different page within the iframe is loaded, not when content is changed dynamically within the iframe.</p>
  
  <p>Here is an example I tried to put together using jsFiddle:</p>
  
  <p>iframe: <a href="http://jsfiddle.net/B4AKc/2/">http://jsfiddle.net/B4AKc/2/</a></p>
  
  <p>page: <a href="http://jsfiddle.net/PmBrd/">http://jsfiddle.net/PmBrd/</a></p>
  
  <p>Any ideas?</p>
