Trying to place a header bar at top of a full page Google Map

0

Trying to place a header bar at top of a full page Google Map but for some reason it keeps pushing the map below the browser view and cuts off.

If I place the top header (#top) above the map, then position .mapCont to start at top:35px, where #top ends, it pushes the map below the bottom of browser and creates a scroll. Why doesn’t it just fit to 100% height regardless of the fixed position layout? It appears to be pushing it 35px below the extents of the browser window.

Cant seem to sort this one out. Thoughts?

Code:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

<style type="text/css">
  html { height: 100% }
  body { height: 100%; margin: 0; padding: 0 }
  #map_canvas { width:100%; height:100%; background: #111 url(../images/loading.gif) no-repeat 50% 50%; z-index: 1; }

.mapCont { 
     display: block;
     height:100%; 
     width:100%; 
     position:fixed;
     top:35px;
     left:0;
     background-color:#111;
     z-index: 0;
}

#top{ 
    height:35px;
    width:100%;
    background: url('../images/finals/wood_top.png') repeat-x;
    display: block;
    position:fixed;
    top:0;
    left:0;
    z-index: 100;
}

.headerLine {
    height:14px;
    width:100%;
    background: url('../images/finals/headerLine.png') repeat-x;
    display: block;
    position:fixed;
    top:31px;
    left:0;
    z-index: 99;
}

</style>
