Cascade Framework

Cascade Framework is a free CSS framework for creating websites and web apps. Similar to Bootstrap and Foundation, it contains a wide range of HTML and CSS-based interface components, as well as optional JavaScript extensions.

John Slegers wanted to create an alternative that offered more flexibility and better performance without cutting back on features. He came up with the name Cascade Framework for his project and released it under the MIT License in March 2013.

Cascade Framework 1.x is written in pure CSS. It supports responsive design and all modern browsers as well as IE6+. For an optimal balance between footprint and flexibility, it implements a modifier design pattern inspired by SMACCS and OOCSS.

As of May 19, 2014, a Cascade Framework-based Drupal theme has been added to the Drupal website sandbox as a sandbox project.

As of October 29, 2014, Cascade Framework Advanced has been released. This Open Source project integrates Cascade Framework with JQuery UI.
