WordPress core provides custom CSS functionality in the customizer that’s specific to the current theme; you can switch themes freely with each theme’s additional CSS remaining in place. This is particularly useful on multisite networks, where it’s often impractical to use child themes to save customizations for each site. Unfortunately, custom CSS is not visible to site admins on multisite networks by default because they are not trusted with unfiltered 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.

- Network Activate the plugin through the ‹Plugins› menu in the network admin
- (Non-super) Admins can now manage their own CSS for the customizer for their site
Why is the plugin necessary?
Core can’t guarantee that CSS is properly sanitized when saving it in the database, and the associated capabilities for managing CSS are equivalent to those for posting unfiltered html. Site admins do not have this capability, so they can’t manage CSS as a result. However, in most cases this is an acceptable tradeoff for providing custom CSS to site admins, particularly on trusted networks (open networks are encouraged to take greater precautions and consider other solutions besides this plugin). Note that super admins can access custom CSS for any site on the network without this plugin.
Because this plugin only provides access to a core feature for more users, all feature requests and non-capability-related support questions apply to WordPress core and not this plugin.
