jquery scroll div only if parent is taller
<p>How can I calculate the height of the parent so that the left div is only animated if there is empty space below itself. I have tried to calculate the parents height is greater then the question height + the margin-top. </p>

<p>This is a simplified version of the code: <a href="http://jsfiddle.net/rewsn/6/" rel="nofollow">http://jsfiddle.net/rewsn/6/</a> as a example. Although in the real version the questions/answer are changed via AJAX so this is the reason I need to calculate the height each time. </p>
