✨ Why not other frameworks?

Even with a multitude of CSS frameworks, some are either too basic that require lots of custom styling and some are too bogged down with a lot of styles that don't end up getting used. Cirrus is meant to bridge a gap between boilerplate stylesheets and UI frameworks.

  • ⚡️ Lightweight - Cirrus consists of a single minified file using only 10.3kb and 17.2kb respectively.
  • 🎁 Beautiful Components - Construct your web app or website using by composing beautifully designed components.
  • 💎 Clean - Styles are easy to follow and written using BEM Notation.
  • 📱 Responsive - Fully responsive by design.
  • 🚢 Modular - Import what you need.

📟 jQuery

  • It is possible to use these components without jQuery in other frameworks like Angular and React by mimicking the behavior of toggling the class.
