Class & Element Mixins
NOTE: This wiki page is dreadfully out of date. Please update me!
Until then go to the source:
Class mixins provide classes or define styles for elements. These will be scoped according to the selector you mix them into.

No class or element mixins are provided by this module.

Style Mixins

Style mixins provide styles to the selector they are mixed into.

+clearfix	If an element contains only floated elements, use mixin to make sure the bottom falls below the contained elements.
+nowrap	Because white-space: nowrap is too much typing, don’t you agree?
