title: Display affected by drop down using CSS
body: <p>I've got a nav bar configured to hide drop down elements (using <code>display:none</code>) until hovered over when it will show as a drop down (using <code>display:block</code> at <code>a:hover</code>).  It all works great except the "divs" below it are pushed down when drop down displays.  How can I get the "divs" to remain in place regardless of the display of the drop down items?  </p>
  
  <p>Thanks!</p>
