Material Design is Google’s new visual design language. It was introduced at the 2014 I/O Conference in June, and it’s beginning to find real traction in all areas of the design community.The free online documentation is available for everyone and it offers so much insight into what Material Design is and how it works. More importantly, it offers plenty of design lessons for us all; it’s interesting, informative and innovative. There are guidelines on what to do, and what not to do, for just about anything you can think of, from button size and placement, to animations.
