In contrast to skeuomorphic design, flat design focuses on simple shapes, colors and typography to emphasize clarity and usability. It was a term coined by Allan Grinshtein of LayerVault in his post "The Flat Design Era," published last year. The release of iOS 7 proved flat design is no longer a passing fad, but rather a step forward.
The flatness of style means simplifying interface elements, removing extraneous elements and decoration — such as bevels, gradients and textures — to create a crisp, clean design that focuses on hierarchy.
