title: margin from heading pushes div down
body: <p>Can anyone explain why the div is being pushed down?  It seems like the top heading margin should push against the top of the div, not the browser window.</p>
  
  <p>Wrapping another div around the div makes no difference. </p>
  
  <p>But if I add <em>padding-top:1px;</em> to the div the problem goes away!</p>
