Reply To: How to change/customize the background color on a separate page

You can add the page id in your css and then add the background color you want for that particular page.

Example, your contact page ID is 63, so if you add this to your css it will show up with a white background for that particular page –

.page-id-63 {
	background: #fff !important;
}

You can do the same for your other pages by finding out the ID and adding the backgrounds.
