<div class="content wysiwyg-content">
My web page has 3 sections, header area (height 50px), central body area (height 300px) and footer area (height 50px). it will always remain the same.<br />
<br />
I have inserted a div between the central body and the footer, and its height is zero by default. <br />
<br />
I want to dynamically set its height when the page loads, so that the TOTAL height of all the elements above always fills the browser screen height for all standard screen sizes. <br />
<br />
I know how to do this, but i am having difficulty finding the browser height. there are compatibility issue in IE, and also i am getting incorrect results. Please tell me the best way to achieve this
