At this years Google I/O, Google has introduced a brand new design style that will slowly be rolling out across all of its services and products including it's online services such as Gmail and it's mobile Android OS.
The new style is being called Material Design.
This new style has been specially developed to give users a similar experience across all Google products, and especially different screen sizes.
The style features a style that gives interfaces more depth by using lots of cards and animations to give a smooth and logical experience.
Most notable is how flat and vividly coloured everything is. These colours will even adapt to content apps produce.
