I'm missing something here (or in the wrong place)

CSS

I'm trying to get the information in the body to expand with the background image, as well as the footer to be on the bottom as it expands with size of the font being enlarged.

i'm a newbie to CSS, so any help or pointing me in the right direction would be greatly appreciated.

thanks.
