add_editor_style not working

Question

I created a style sheet

editor-style.css

I want to load this css file using add_editor_style() function,

In my functions.php

function my_theme_add_editor_styles() {
    add_editor_style( 'css/editor-style.css' );
}
add_action( 'after_setup_theme', 'my_theme_add_editor_styles' );

I also tried this solution

add_editor_style is not loading in frontend. Any solution?

Answer 1

You shouldn't need an action to add an editor style. Simple add the following anywhere in your functions.php:

add_editor_style('css/editor-style.css');

Answer 2

You need to do two things (see additional add_theme_support):

add_theme_support( 'editor-styles' );
add_action('admin_init', 'el_add_editor_styles');

function el_add_editor_styles() {
    add_editor_style( get_template_directory_uri() . '/css/editor-style.css' );
}

Answer 3

Use an absolute path for the stylesheet:

add_editor_style( get_template_directory_uri() . '/css/editor-style.css' );

Answer 4

For me, this is what worked

add_theme_support( 'editor-styles' );
add_editor_style( 'css/custom-editor-classes.css' );

I didn't need to put the absolute path or use add_action, but I did need to include add_theme_support. I'm guessing this may vary based on parent theme.
