Anybody knows why the following code fails to work? I need a dynamic height for a fixed width div that may descend below past the viewport.

 <script type="text/javascript">
function findheight(){  
  var div = document.getElementById('bg');
  var height = document.scrollHeight;
  div.style.height = height + 'px';
}

  </script>     
</head>

<body onload="findheight()">
    <div id="bg">

Is there another way around this if not?? Any help is appreciated. Thanks

    You could achieve this using javascript, you have to use the ‘offsetHeight’ method. 

    function getHeight() {
    var height = document.getElementById('test').offsetHeight;
    alert(height);
}

    Here is a sample fiddle
