Modify the Additional CSS section (adding a disclaimer)

Question

I was trying to dig into this deeper, but I couldn't find any useful ways/hooks to add a little disclaimer above the Additional CSS code editor in the Wordpress Customizer. If anyone has a starting point of how i can add something simple like that, it would be greatly appreciated.

The section I am talking about is wp-admin > Appearance > Customize > Additonal CSS

We basically want to add a disclaimer to our clients about using that section, and I wanted to do it the Wordpress way, and not hack anything using jQuery (to add it) or in core.

Answer 1

Yep. I was able to show it by default using:

<?php add_action('customize_controls_print_styles', function() { ?> <style id="custom-css"> #sub-accordion-section-custom_css .description { display: block !important; } </style> <?php }); 

Thanks for your help!

You will need the get_section method of the $wp_customizer class. Like this:

add_action( 'customize_register', 'wpse261932_change_css_title', 15 ); function wpse261932_change_css_title () { global $wp_customize; $wp_customize->get_section('custom_css')->title = __('Additional CSS. Be careful!', 'textdomain'); } 

For some reason the description has display:none on it in this panel, even though that would be a more logical place to show your disclaimer.
