WordPress editor custom styles

Using the following code I'm trying to add some CSS to the default Gutenberg editor in Wordpress:

function editor_style() {
    add_theme_support( 'editor-styles' );
    add_editor_style( 'editor-style.css' );
}
add_action( 'after_setup_theme', 'editor_style' );

While this works, it also makes the editor look weird:

It seems as if all styles are removed other than those from my custom stylesheet. Is this intentional? I'm using Bootstrap in my theme. Should I include this here too?

Solution

  • I've found the issue. In the block editor WordPress includes some 'on page' <style> tags.

    These inline style tags are removed when using your own editor style. You can fix this by adding the inline styles directly on top of your custom editor style file (place this on top of your editor-style.css):
