/** Hauptnavigation
-------------------------------------------------------------------------------------------------- */
ul#nav {
  background:#5D5D5D url(../images/nav-bg.jpg) top left repeat-x;
  list-style:none;
  font-size:1em;
  margin:0 auto;
  border:solid 0px red;
  width:925px; height:48px;
}
#nav a:link,
#nav a:visited,
#nav a:hover,
#nav a:focus,
#nav a:active,
#nav strong {
  float:left;
  display:block;
  padding:8px 10px 8px 20px;
  color:#FFFFFF;
  background-color:transparent;
  text-align:left;
