This UI toolkit was built by the team at Cloud Four for the redesign of Ceasefire Oregon. It's a highly-modular design system for rapid web page development. It contains different materials that can be assembled into more complex page layouts, along with code snippets, documentation and style guidelines.
The Sandbox includes mockups, demonstrations and proofs-of-concept.
