Creating a child theme in WordPress empowers you to customize your website without directly modifying the core theme files, ensuring future updates don’t overwrite your changes. This approach provides a safe and efficient way to tailor your site’s appearance and functionality to your unique needs.
A child theme acts as a layer on top of the parent theme, inheriting its styles and functionalities. By creating a child theme, you can modify the existing design, add custom features, and implement new layouts without affecting the parent theme’s core code.
This modular approach allows for easy updates and maintains the integrity of the original theme.
Understanding Child Themes

This approach ensures that your modifications are preserved even after theme updates, preventing potential conflicts or loss of customization.
