title: Can I keep a DIV always on the screen, but not always in a fixed position?
body: <p>I have a master form for my website, and I want to dock a div to the top of the content area inside the master form. This div should always be visible despite scroll position. Is this possible?</p>
  
  <p>A picture would explain it better.</p>
