How to Create a WordPress Child Theme
Having a child theme is necessary for every WordPress site and installing one is the first thing a WordPress user should do upon creating a new website.
Why? Because at some point in the future, you’ll find the need to directly edit your theme files. And if you don’t have a child theme, all the changes you make to your theme files will be lost every time you update your theme, requiring you to implement the same changes over and over again.
