title: Need CSS sidebar height to expand with content
body: <p>I have a two column layout, with a gray sidebar on the right. I need the sidebar's height to expand when the height of the left column is increased (due to content being dynamically expanded). I can make the sidebar fit a static page, but I cannot get it to increase in size with the rest of the page. Did some Googling, but couldn't find a work-around that worked for me.</p>
  
  <p>Does anyone know how to do this?</p>
