center column padding top and bottom

i want the background on the site white but on the static home page I want it burgundy. I made an image that fills the home page but I have a white area 15px high at the bottom, between the image and the footer. I have removed all the instances of padding I can find but cannot remove it. In

Center column style

I changed the background to burgundy and that changed the background and made the white at the bottom disappear but it changed the background to burgundy for the whole site. Changing it back to white I changed the padding to

padding: 0px 0px 0px 0px;

but it did not remove the padding on the bottom. How can I remove this padding?

Thanks,

Dan
