I need to give site Administrators in a multisite network the ability to add/edit CSS in the Customizer. I found a plugin that does exactly would I need. Multisite Custom CSS – https://wordpress.org/plugins/multisite-custom-css/
“This plugin gives site admins access to the core custom CSS feature by mapping the edit_css capability to edit_theme_options, thereby trusting site admins with unfiltered CSS.”
Is there a way to grant edit_css to roles with URE?
