Are styles included in a stylesheet using add_editor_style loaded in the front end?

Question

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" );

UPDATE

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' );

Answer 1

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

<?php
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.
