CSSOff is a yearly competition for frontend developers to measure their skills and expertise. I participated in 2013 together with 8000 others. The layout was rather complex and more print oriented. It was supposed to be responsive and as a bonus I made it fairly accessible. Since it left open many questions it was easily interpreted in many ways. So also the judges had quite some works this year. As of right now, 6 months after submission, their are no results. UPDATE: 2017 and no results. I guess this is dead. Good practice though.
