Allows administrators to inject CSS into the page output based on configurable rules. It's useful for adding simple CSS tweaks without modifying a site's official theme -- for example, a 'nighttime' color scheme could be added during certain hours. The CSS is added using Backdrop's standard backdrop_add_css() function and respects page caching, etc.
This module is definitely not a replacement for full-fledged theming, but it provides site administrators with a quick and easy way of tweaking things without diving into full-fledged theme hacking.
The rules provided by CSS Injector typically are loaded last, even after the theme CSS, although another module could override these.
Install this module using the official Backdrop CMS instructions at https://backdropcms.org/user-guide/modules
Visit the configuration page under Administration > Development > CSS Injector (admin/config/development/css-injector) to add CSS rules and to configure the settings.
