YAML CSS Framework — for truly flexible, accessible and responsive websites

Where it comes from

A brief history

When YAML was released in October 2005, it was conceived as a base for developing flexible layouts, with a strong emphasis on meeting the challenges that result from working with flexible (elastic, fluid) containers and varying units.

This CSS framework has been continually improved and extended over the years, based on the feedback and needs of professional frontend developers. Its code base has proved to be stable under real-world conditions on thousands of websites. Over the years, YAML-based websites won several awards at the German annual accessibility competition «Biene Award».
