title: Position overlay div
body: <p>I have a link in a table cell and when the link is clicked I show a hidden div. </p>
  
  <p>Currently I use position: absolute and z-index:10. It works fine, but I would like to move it a bit to the top and left. When I add top: -10px and left: -10px, the div moves to the position of the window. </p>
  
  <p>How do I make it 10px off the table cell?  </p>
