A lightweight responsive Sass/CSS framework based on flexible box.


Why it's awesome?

  • Basis isn't about a UI framework. Basis provides only basic frame of components. So you build a responsive web page quickly and easy to overwrite with your Sass or CSS.
  • CSS architecture of Basis is FLOCSS. So it is possible a modular approach.
  • Basis has incorporated the concept of vertical rhythm. So you can be a good-balanced design.
  • Basis has many mixins. Usufule mixins and abstract mixin of compornents.
