I developed this extension which allows you to use Sass (SCSS) and Compass easily in your Yii projects:
Extension can do the following:
compile SCSS files on-the-fly
publish compiled CSS files
register published CSS files
External Sass tools are NOT used, compilation is done using PHP compiler.
This extension caches compiled CSS code and prevents recompilation if there is no need in it.
A few words about Sass and Compass:
Sass is an extension of CSS that adds power and elegance to the basic language. It allows you to use variables, nested rules, mixins, inline imports, and more, all with a fully CSS-compatible syntax. Sass helps keep large stylesheets well-organized, and get small stylesheets up and running quickly.
Compass is an open-source CSS authoring framework which uses the Sass stylesheet language to make writing stylesheets powerful and easy.
