For a project I want to add two additional body classes. One would switch the site to a black, white, and yellow high-contrast version, and the other would show a different background image for all posts within a certain category (category-29). This is a custom taxonomy.
I'm struggling to get this implemented. One of the things which is throwing me is the Current Install Class Pro box within the admin panel. I have tried adding my class here on its own, as well as the class plus selectors, to no luck. Do I simply put the bodyclass and selectors in with the custom CSS?
Another thing which is confusing me is the difference between the WP standard
Do I still need to call this in functions.php or does the Current Install Class Pro box create the filter?
