Material design takes off
Google released its Material design language back in June 2014 but the adoption has been a bit slow. However, designers now have a better understanding of Material design and I anticipate they will start opting to use it more in their designs as documentation and examples become more widespread.
Material design focuses around tactile but dynamic elements that remind us of paper and ink. Shadows that are realistic, items that overlap do so with regards to reality, interactions stay inside of material and don’t impact other material around it.
Since we’ve seem to have reached peak flat design, designers are opting for the next thing, and Google offers that up in their Material design language. I anticipate many more sites to follow this same material design aesthetic in 2016.
