Raptor Web Designer allows you to specify different background for the browser, page, header and footer. The background can be either solid fill or image.
Choose Page > Background to change background fill of the page. If you want to change header of footer background, double click it first to enter it and then change the background.
This example illustrates 4 different backgrounds: white header (1), blue page (2), transparent footer without background (3) and website background with solid blue fill (4).
Website background (1) covers entire browser space. It's also placed below all other elements of the page. Choose Website > Background to change it.
Website background image (1) spans from top and the rest is filled with white color (2). Page background (3) is transparent so it doesn't cover website background.
