A subtheme of a WordPress theme is a theme that is created based on the parent theme. Child themes can inherit all the features and styles of the parent theme, but you can add custom code and styles to meet specific needs without affecting the parent theme. Subthemes allow site owners to make custom changes to meet their needs while keeping the parent theme updated, while maintaining the core functionality and style of the parent theme.
The features of the subtopic include:
- Custom styles: child themes can add custom CSS styles to modify the look and feel of the parent theme.
- Custom features: subtopics can add custom features, such as custom widgets or page templates.
- Inheritable parent theme features: child themes can inherit all the functions and styles of the parent theme, as well as any updates made in the parent theme.
- Keep the original theme: child themes can be customized without changing the parent theme to ensure the integrity and updating of the original theme.
