How can I add Custom CSS to my FSE Theme?

If you are using one of our FSE Themes, the Additional CSS panel will not appear anymore by default in the Customizer, as it happened with other themes. To insert custom CSS to your FSE theme, follow these steps:


Insert the /wp-admin/customize.php structure at the end of your URL.

In our example, the URL became: In your case, just replace the website's name with the one you administrate.


Open the Additional CSS panel and start coding.
