This reference implementation of PatternFly is based on [Bootstrap v3](http://getbootstrap.com/). Think of PatternFly as a "skinned" version of Bootstrap with additional components and customizations.

// Labels

.label-variant(@color) {
  background-color: @color;

  &[href] {
    &:hover,
    &:focus {
      background-color: darken(@color, 10%);
    }
  }
}
