patternfly/dist/js/patternfly-settings-base.d.ts

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.

interface Patternfly {
  pfBreakpoints: {
    tablet: number;
    desktop: number;
  };
}
interface Window {
  patternfly: Patternfly;
}
