What Are Child Themes
From the WordPress back end, a child theme doesn’t behave any differently. You can find and activate it under “Appearance” → “Themes,” like you would with any other theme.
A child theme depends completely on its parent in order to work. Without its parent theme present, it will not do a thing and cannot even be activated. Because a child theme isn’t a standalone entity, but instead modifies or adds to the files of an existing theme. It uses everything present in the parent theme and allows you to make changes and customize your WordPress theme without ever editing the main theme. So you can alter styles, functions, layout, templates… However, without the parent theme being present, none of it will work, and you will get theme updates without losing your changes
Child themes are completely portable, and you can use it on as many sites as you like. You can download them and install them on another WordPress site. You can even submit your child theme to the WordPress theme directory for others to use if it meets certain standards.
