The simplest answer is: you can use whatever stylesheet you want for the editor. editor-style.css
is just the default stylesheet loaded if none is passed to add_editor_style()
.
This will load the specified stylesheet:
add_editor_style( 'some-stylsheet.css' );
This will load editor-style.css:
add_editor_style();
Use whatever better fits your needs.
By the way, it is better practice to add the editor stylesheet using after_setup_theme
action, not init
, as it is something specific for the theme:
add_action( 'after_setup_theme', 'cyb_theme_setup' );
fucntion cyb_theme_setup() {
add_editor_style();
}
