I am looking to create a mobile-only child theme for my site on a separate WordPress install but which is on the same server at the main install.
Example of folder Structure:
mysite
wp-content
Themes
parent-theme
tablet
wp-content
themes
child-theme
Would I have to duplicate the parent theme into the Tablet theme directory and repeat every time the parent theme is changed or is there a solution in which the child-theme can use the parent theme from the main install directory?
Note: WP Multisite is not an option due to all sites sharing the same database.
