A child theme is the best way to apply custom code changes to your website without modifying the main (parent) theme directly. This ensures that your customizations remain intact even after updating the parent theme.

Key Benefits of Using a Child Theme:

Safe Updates – Your changes won’t be lost when the parent theme is updated.
Customization Flexibility – You can override specific files and functions without modifying the entire theme.
Easy Maintenance – Makes debugging and updates more manageable.

Important: While child themes allow for basic customizations, they require some coding knowledge (HTML, CSS, PHP). If you need advanced modifications, it’s recommended to hire a developer.

The download and installation process for a child theme is the same as that of the parent theme.
