In the CSS make sure to find the ID of the page for the home page this is home for other pages you can find the ID of the page or post by going to the edit page and looking for the post=”#” for example http://x.hoover.ws/wp-admin/post.php?<strong>post=6608</strong>&action=edit more information on how to locate the ID can be found in this KB article – http://theme.co/x/member/kb/how-to-locate-post-ids/

Once you locate the ID add some CSS code under Appearance -> Customize -> Custom -> CSS

body.page-id-6608, .page-id-6608 .x-logobar, .page-id-6608 .x-navbar, .page-id-6608 footer {
background-color: red;
}

Change 6608 to the page ID you want to customize.

If I misunderstood and you just want the content in the main content are then just use:

body.page-id-6608 {
background-color: red;
}

Change “red” for whatever color you are looking for either in its short name or hex value.

I hope this helps.
