patternfly/components/bootstrap/less/mixins/progress-bar.less

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.

// Progress bars

.progress-bar-variant(@color) {
  background-color: @color;

  // Deprecated parent class requirement as of v3.2.0
  .progress-striped & {
    #gradient > .striped();
  }
}
