Footer size and position...

Now I love the theme, but I am a little confused as to why the footer is set to 370px?

I changed it to 50px like so:

* html .FooterContain { height: 370px;} to * html .FooterContain { height: 50px;}
and
.FooterContain { min-height: 370px; } to .FooterContain { min-height: 50px; }

But now I have a huge white space below the footer.

Can someone help me glue the new 50px footer to the bottom of the page. Because right now the main page doesn't have enough content to push it to the bottom.

Thanks!
