Hello,
I have seen your screenshot. If you want to change the background color of your pre footer area. You can use the below CSS code in global custom CSS area under theme settings >> custom CSS:
.woodmart-prefooter {
background: red;
}
OR
If you want to change the wrapper background color of product page. Then you can use the below CSS code:
.single-product .website-wrapper{
background: red;
}
I used red color just to set an example for you. You can use any different color.
Best Regards.
.
