Tops and bottoms

Hey all. I can’t figure out for the life of me why I can’t add a margin above my background pic, add a margin at the very bottom of the page to allow for the popup, or get my page footer to show up. I have some CSS but am not proficient. But I have tried everything I can think of.

The site I am trying to build is at: http://realrockentertainment.com.

Thanks!!!!!!!!!!!!
