The PatternFly Framework includes reference HTML markup and CSS for widgets and selected patterns. You can use this code directly in your project or as a starting point for your own implementation. The framework is built on top of Bootstrap 3 and is licensed Apache 2.0. The PatternFly framework is available in a number of distributions.
This reference implementation of PatternFly is based on Bootstrap v3. PatternFly can be thought of as a skinned version of Bootstrap with additional components and customizations.
Angular PatternFly is a supplement to PatternFly and provides a set of common AngularJS directives for use with the PatternFly reference implementation.
