You can stylize the dashboard admin area with the custom CSS. Here is the snippet code you need to paste into functions.php file. Replace the comment with your custom code.
“admin_head is an action event and can be hooked by add_action hook. The action refers on the admin area and everything you include here will be applied only on the admin side. ”
Does this snippet (still) work?
Please let us know in the comments if everything worked as expected. We have tested this code with the Version: 4.0.1 of the Divi Theme and Divi Friendly Hosting with PHP 7.3 and WordPress 5.2.4.
