What Is a WordPress Child Theme and When Should You Use One?

Learn how child themes help preserve customizations across parent theme updates.

A child theme inherits styles and functionality from a parent theme while allowing site-specific overrides. It can be useful for template changes or custom functions that belong at the theme layer. Small CSS tweaks may be better handled through the customizer or site editor, depending on the theme. Keep changes documented and test after parent-theme updates because template overrides can become outdated.
