title: Detecting when a div's height changes using jQuery
body: <p>I've got a div that contains some content that's being added and removed dynamically, so its height is changing often. I also have a div that is absolutely positioned directly underneath with javascript, so unless I can detect when the height of the div changes, I can't reposition the div below it.</p>
  
  <p>So, how can I detect when the height of that div changes? I assume there's some jQuery event I need to use, but I'm not sure which one to hook into.</p>
