Newbie: Background image is jQuery Mobile page?

Hi,

Is there a way to have a background image in a jQuery Mobile page? The idea is to have a nice image (say a flower) that is shown as background of a page including that of any listviews, tables, grids and other controls on the same page. Is that possible and, if so, is there an example of doing that (w/o plug-in)?

Thanks in advance and regards
