There are several ways to add custom CSS to your WordPress theme and front-end, but those methods won’t work for your back-end as well.


So, if you want to add custom CSS to your WordPress admin area, you’ll need to use another method.

This method consists of installing a simple plugin called Add Admin CSS, which is created by Scott Reilly!
