topic background

If you only want to style the body of a topic (and not much beyond), slapping a class on the body tag and styling that class with some background image/color/gradient should be fine:

(here I just directly insert it as a style, but the style should be defined in the CSS. I also presume you'll be using background-image instead).

If you're looking for pdf page customisation instead, you can edit the page layout in the pdf template.

(With some workaround)

That would depend on what version of RoboHelp you are using. You haven't said which version of RoboHelp you are using. Please always start a thread with this information. Please go to Help > About and include the full version number.

Also how you want to customise it. A background image is easy, you just add a background colour to the body tag in your CSS. As far as I recall background images don't work. I would have to look that up.
