In WordPress, a “parent theme” is a complete, standalone WordPress theme that is used as the foundation of the website.
A parent theme contains all of the necessary files and code to create the basic design and functionality of a WordPress website, while a child theme is used to make customizations and modifications to the parent theme without affecting its core functionality.
When you create a child theme in WordPress, it inherits all of the features and functionality of the parent theme, allowing you to build upon it and make changes as needed. You can use a child theme to modify the design, layout, or functionality of your website, without having to modify the original code of the parent theme.
