Hi all,

I'm unable to get rid of the blank space before the header of the site begins:

dev.msl.org

Relevant segment of stylesheet below (I apologize for the long segment, but I'm really not sure where the issue is:

body {
  margin:0px;
  padding:0px;
  font-family:Georgia, "Times New Roman", Times, serif;
  font-size:80%;
  background-image:url('images/background.jpg');

  background-position:top center;
  background-color:#3073b4;
}
h1, h2, h3, h4 {
  margin-top:0px;
}
h2.pagetitle {
  color:#003366;
  padding-bottom:5px;
  margin-bottom:10px;
  border-bottom:1px solid #003366;
