I am writing a stylesheet that will help show the content in the TinyMCE editor look more like it would appear on the front end of the website using the add_editor_style function in the WordPress theme functions file. I may even end up adding a few style rules in the editor-style.css file just to be used on content.

So I am wondering if the styles added to the editor-style.css stylesheet are also loaded on the front of the website when the page gets rendered? I checked the WordPress documentation and I didn't see anything that specifically stated one way or the other.

add_editor_style( "editor-style.css" );


Here is the actual code from the themes functions file:

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

Below is the full code to include the editor style in a common way.

function my_theme_add_editor_styles() {
add_editor_style( 'custom-editor-style.css' );
add_action( 'admin_init', 'my_theme_add_editor_styles' );

When you are adding the custom editor style, you need to use admin_init hook which is triggered only when you are inside the admin panel. So the stylesheet will not load in the front end and is limited to admin dashboard.

  • What if after_setup_theme is used in the add_action hook instead of admin_init? Will the editor styles be loaded on the front end then while still being loaded in the editor? I updated my question to show what I presently have in my theme. Apr 28, 2015 at 19:12

    I believe that styles added with add_editor_style do not appear in the front-end regardless of where they are loaded.That said, you should use the admin_init action hook since it will be more efficient and only run in the admin area =)

  • I just checked the code using after_setup_theme, it doesn't load in front end either. So we can be assured add_editor_style doesn't append style to front end.
