I know that there are tons of answer out there. I spent many many hours trying to figure out what it not working.
I want to have a sticky footer. the html structure is like this
<body>
<div id=container>
<div id=header>
</div>
<div id=body>
<div id=left>
</div>
<div id=center>
</div>
<div id=right>
</div>
</div>
<div id=footer>
</div>
</div>
</body>
and a link with the css and the content link
