Cirrus
The SCSS framework for the modern web
...Forget bundling tons of JavaScript with each component. All styles require no JS for interactions/functionality (see Modals, Dropdowns, etc.). Add additional components, remove utility classes, disable features, etc. Cirrus takes a generative approach to building your stylesheets. A large number of features with a minimal footprint. Fully responsive by design. Getting started with Cirrus is a few commands or lines of HTML away (depending on how you want to import it). The framework is designed to be pluggable into any new or existing projects.
