How does Child Theme work?

A Child Theme is stored separately from the parent theme and has its own functions.php as well as style.css file. The best way to understand the child’s theme is to think of it as an overlay. When any visitor visits your website and the browser loads it, WordPress first loads the sub-theme and then finds the missing style and functions from the parent theme. In the end, you will get the best of the design without losing the theme’s core functionality.

A parent theme is also known as the Theme Framework that contains its own filters and hooks. In this way, we can design the custom WordPress website using the child theme with the parent theme as the backup in a short period of time.
