title: Get Height of a div Which is Absolute-Positioned and Hidden
body: <p>I have been reading and trying to solve this problem, but I can't find a solution.  </p>
  
  <p>I'm trying to get the height of a div, to update another div's height and make cool jQuery animations. It's all triggered by an ajax request (which works ok).  </p>
  
  <p><a href="http://jsfiddle.net/97Xx5/2/" rel="nofollow">Here is a live example</a>  </p>
  
  <p>I don't know how to get the height of the <code>#bigBox</code>, because it always return 0.</p>

  <p>All the soloutions worked, but they didn't do what I expected.
  I need to calculate the height after the <code>#bigBox</code> fade out.</p>
  
  <p>Finally I managed to do it.</p>
  
  <p>I change the class <code>.toToggle</code> to the div <code>#bigBox</code>, instead of beeing in it's parent div. This was done to avoid the parent beeing <code>display: none;</code>. Now the same element is hidden, so it works</p>

  <p>Thank you all! :D</p>
