What is boba?

boba was born out of frustration with other CSS design frameworks.

  • Lightweight at just ~10KB gzipped
  • Modular; easily add or remove components or classes
  • Semantic class names to speed up development
  • Responsive, flexbox-based grid system
  • Vibrant, fresh color palette
  • No JavaScript

Is boba for you?

Of course it is!

Be it a smaller project or production-scale website, boba has all of the utilities and components that you need to get started quickly and efficiently. In fact, our entire website, including our documentation, is built entirely using boba's built-in classes.

Getting Started


boba can be installed manually, requested via CDN, or installed via NPM / yarn.

Check out our installation guide for more information.

Browser Support

Boba uses autoprefixer to automatically generate browser-specific prefixes needed to support the latest two versions of each browser.

Browser Supported Version
Internet Explorer 10+
Edge Last 2
Mozilla Firefox Last 2
Google Chrome Last 2
Safari Last 2
Opera Last 2

Although most of boba is compatible with Internet Explorer 10+, some HTML5 / CSS3 features may not be fully supported.

You can compile your custom version of boba. Check out our documentation for more information.
