How to make a custom background for a certain section in wp?

Question

WordPress

Hello I am new to wp. And I'm wondering how to make a custom background for a specific section.

Now I am using . But the image is set on the body. Is there any way to set the background to a specific section? add_theme_support( 'custom-background' );

Answer 1

here's the customizer, but I still tend to think that the customizer is for global settings and not for the settings of a specific section of a specific page.

_ without arbitrary fields in principle, so I even make settings through them and not through the customizer.
Again, what is the section done on? Gutenberg is good at backgrounds, all builders can too.
