Saffron is a collection of Sass mixins and helpers that make adding CSS3 animations and transitions much simpler. Just include a mixin in your Sass declaration, then set any configuration using variables and mixin parameters. With Saffron, you have complete control over how your animations and transitions should behave.
Try out some of the animations by clicking on the ring above, and when you're ready to use Saffron on your own project, install it using the gem or Bower.
