cssSweet is a suite of tools for processing (S)CSS. It comes with several output modifiers to modify CSS values, and a plugin that concatenates and processes (S)CSS from specified Chunks and outputs to a minified CSS file. version 2+ also concatenates and minifies JS with a 2nd plugin.

The documentation site is here: http://sepiariver.github.io/cssSweet

as well as here: http://rtfm.modx.com/extras/revo/csssweet (this one needs updating)

Example Use Cases

• - Use system or context settings to store primary colors in a site's color scheme, then process all other color values relative to these, so you can shift the entire color theme by modifying a few settings.
• - Use in conjunction with ClientConfig to give site owners a nice UI to manage CSS styles--but only the ones you expose, and only in the manner you choose!
• - Author MODX "themes" that are customizable by the end user.
• - Use other MODX tags & placeholders in your CSS--limitless possibilities! Utilize "dynamic CSS" without the performance penalty, because the plugin writes the static CSS file on the Manager Clear Cache and Chunk Save actions, not per request.
• - Manage your Sass, CSS, and JS development workflow right from inside the MODX Manager.
• - Add a code editor like Ace, and you can use MODX as your IDE for front-end development.
