Set Google Maps Container DIV width and height 100%

Solution 1:

You have to set all parent containers to a 100% width if you want to cover the whole page with it. You have to set an absolute value at width and height for the #content div at the very least.

body, html {
  height: 100%;
  width: 100%;
}

div#content {
  width: 100%; height: 100%;
}

Solution 2:

Setting Map Container to position to relative do the trick. Here is HTML.

<body>
    <!-- Map container -->
    <div id="map_canvas"></div>
</body>

And Simple CSS.

<style>
html, body, #map_canvas {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
}
#map_canvas {
    position: relative;
}
</style>

Tested on all browsers. Here is the Screenshot.

Solution 3:

Very few people realize the power of css positioning. To set the map to occupy 100% height of it's parent container do following:

#map_canvas_container {position: relative;}

#map_canvas {position: absolute; top: 0; right: 0; bottom: 0; left: 0;}

If you have any non absolutely positioned elements inside #map_canvas_container they will set the height of it and the map will take the exact available space.
