angeloa on "Can't get my footer at the bottom"

Hi guys,

Whatever code I use, whatever tutorial I follow, I can't manage to put my footer at the bottom of my custom made theme. This is my theme:

http://plexus-orthopedie.nl/wordpress

Location of the footer:
body > div#page > footer.site-footer

I've tried this, but it places the footer at the bottom of my browser display, so when a page is scrollable, it's placed on top of content.

footer.site-footer {
position:absolute;
bottom:0;
height:100px;
width:100%;
}

I hope someone has a solution.
