How to define body background with additional banner?

[toplisek]

I have set background for menu header with X-repeat like:
#header1 {
background: url("../images/header_background1.jpg") repeat-x scroll center top transparent;
}

Issue is the following:
if I set banner on the right hand side under this header it will be top header background till size of display (X repeat). If I set banner larger than this display resolution it will not be top background expanded. How to solve this as currently it is EMPTY blank space for the difference. Should be image enlarged for the background (header_background1.jpg)?

Hi toplisek, I'm coming to this late, but have looked at this several times and am still not sure I understand what you want to achieve. Are you wanting to set the (second) banner on the right hand side so that it is wider than the display resolution?
