Community Q&A
Where is the best place to add custom CSS in WordPress?
The safest place is the ‘Additional CSS’ section in the WordPress Customizer, as it is theme-independent and persists through updates.
Should I use a plugin for custom CSS?
Plugins like Simple Custom CSS are useful if you need to manage large amounts of code, but the built-in Customizer is sufficient for most users.
Why is my custom CSS not showing up?
This is usually caused by browser caching or server-side caching plugins; clear your site cache and browser history to see the changes.
