A child theme is a sub-theme that inherits all the functionality and style of the main theme, also called the parent theme.
Child themes in WordPress provide a secure method to customize a theme without directly editing it. When the parent theme gets updated, any modifications made in the child theme will be retained and applied to the updated version.
Sometimes, the theme includes a child theme, but you might need to create one manually.
To create a child theme, make a new folder in the wp-content/themes/ directory, and it’s a good idea to name it with “-child” at the end for easy identification.
The child theme directory should include at least:
You should also copy the files you want to change from the parent theme into the child theme directory.
Important note: Keep in mind that this method works for the core files of a WordPress theme, known as template hierarchy files. Any additional files created by the developer may not always be editable within the child theme.
Why Use a Child Theme?
Using a child theme to maintain up-to-date security and updates is certainly important, but it also offers the advantage of introducing additional features and templates that might not be present in the parent theme.
Using a child theme is a good idea for two main reasons:
1.Security and Updates:- It helps you keep your website secure and up-to-date. When you update the parent theme, any changes you make in the child theme won’t be affected. This prevents your customizations from being overwritten.
2. Adding Extra Features:- You can use a child theme to easily add new functions or templates that aren’t available in the parent theme. This lets you expand your website’s capabilities without altering the original theme.
