Change the theme CSS in WordPress
Required: Before making any changes to a WordPress theme, create a child theme, install and then activate it. If you don't have a child theme, every time your theme updates, any changes you made will be undone.
Warning: Make sure to backup your WordPress site before adding any CSS, because you can accidentally break your site's appearance.
You can make changes to the CSS of your theme from within WordPress.
- Sign in to WordPress.
- Go to Appearance and select Theme File Editor. A popup message will appear warning you about making direct changes to these files. If you made a backup and activated the child theme, select I understand and continue.
- Make your CSS changes or additions.
- Select Update File.
