Make a child theme for WordPress.

Updated: Aug 25, 2021

A WordPress child theme is a replica of the theme you're currently using. It's a protected area where you can make changes to theme files, instal plugins, and test your code without having to touch the theme files directly. If you want to learn how to make a child theme, you can use this guide.

To make a child theme, you must first create a folder for it in your themes directory. The only file you need in this folder is style.css. You can define the parent theme in the header of the style.css file by adding a template line to the comment code where the theme name is put. Because this style sheet comes after the parent's style sheet, it will override any other style sheets.

The child theme must be active in order to implement the changes. Any functionality that hasn't been replaced by the child theme will still be available in the parent theme.

What is the significance of a child theme? Be careful if you're learning to edit theme PHP codes, which is the type of coding language on which WordPress is based.

The default code that comes with each WordPress update will overwrite all of your customised code in the next update. All of your hard work would have vanished by the time you realised it.

The parent theme is not supposed to overwrite the child theme. As a result, when you update the parent theme, the code you wrote in the child theme will remain unchanged. The child theme will be updated as well if the parent theme is updated.

As a result, creating a child theme allows you to enjoy the best of both worlds, namely, regular updates while retaining your customised PHP scripts.
