Hi,

Which pages exactly? Could you provide an URL directly to your page?

Of all the pages to be created. It is to maintain that design for all pages

Generally it's not possible, white and grey background on homepage are from different widgets, so you can't do this only for mainbody content. (but you can use e.g. widgets from bottom1-bottom1 positions and assign them to specified pages.
