Select your content block to "The Section" blocks, so you can give the selected content a different wrapper. There are "Section Option"and "Builder Section". In "Section Option", you can choose a different background color from main content or even image. Also you can add padding bottom and top to separate it with other content outside this block. We will tell you about "Builder Section" later.
Now, we go to "Builder Section" in "The Section" option that I have explained you.
