This plugin allows you to specify CSS files that will added to the headers. Declare a CSS fiel to add for every page on the frontend and another for the backend. Declare component-specific CSS files that will be included only on pages based upon that component.
Backend Advantage: iCue developed this plugin so that CSS can be applied to tailor backend forms and improve usability - and at a per-component basis. For example, forms with fields that are not needed by the client can be hidden with CSS rules.
This plugin works for Joomla versions 2.5 and 3.x.
