I am currently using a pre-built site: Firm4 and having trouble figuring out to have a background color so the content will be visible
Here is my test post: https://wp.polypay.com/2021/10/test/
Thank you and looking forward to an answer.
You can set the background color for the content in the Muffin Builder in the section options.
For the rest parts, you will have to write a custom CSS code and place it in Betheme -> Theme options -> Custom CSS & JS -> CSS. If you need help with writing it, please, let me know.
