title: How to make Resizable Panels?
body: <p>I need to build a page that looks like Mac Mail or an Outlook Inbox. where the one page has a top panel and a bottom panel, and there is a divider in between that you can use to re-size, to either make a panel higher or shorter. </p>
  
  <p>What's the standard jQuery/CSS technique for accomplishing this? I've never done this before so I am interested in your suggestions or any surprises that you might have encountered before.</p>
