:sparkles: Features

  • :art: Beautiful Components - Beautifully designed components come right out of the box for rapid prototyping.
  • :balloon: Sass First - Forget bundling tons of JavaScript with each component. All styles require no JS for interactions/functionality (see Modals, Dropdowns, etc.).
  • :rainbow: Configuration at its Core - Add additional components, remove utility classes, disable features, etc. Cirrus takes a generative approach to building your stylesheets.
  • :zap: Lightweight - A large amount of features with a minimal footprint.
  • :iphone: Responsive - Fully responsive by design.

:dart: Supported Browsers

Cirrus relies on What CSS to prefix? to determine which selectors need prefixes.
