Patternfly - A community of designers and developers collaborating to build a UI framework for enterprise web applications

The PatternFly library is a collection of UI design patterns. Design patterns are recurring solutions that solve common design problems and provide a common language for people who create user interfaces. In general, patterns do not specify requirements, but rather, present recommended solutions to design problems. PatternFly patterns build on that approach by additionally considering the needs of complex enterprise IT software, and the habits and motivations of its users, in their recommendations.

This reference implementation of PatternFly is based on Bootstrap v3. Think of PatternFly as a "skinned" version of Bootstrap with additional components and customizations. PatternFly is meant to be used as a replacement for Bootstrap, so don't include the Bootstrap CSS if you are including the PatternFly CSS in your project.
