So I have a css file that is called
blue.css and a universal one called
style.css I have a few css colors inside a
/css folder. How do I get all those css files to show up in my Admin panel editor?
add_editor_style() function in your functions.php:
add_editor_style( 'css/blue.css' );
You can call that function multiple times to load additonal stylesheets in to the admin editor.
