Flat design is a graphic design style that puts the product and content first. This minimal approach removes unnecessary details in an interface and boils the design down to the core functionality. There are no shiny buttons, bevels or bezels, and especially no photorealism (also known as skeuomorphism, like the torn pages on the iPhone Notes app). By including only the elements that are necessary, a designer can create an elegant and responsive easy-to-use interface quickly. It’s an incredibly popular style nowadays. So here are 12 Free Flat CSS & PSD UI Kits that can be utilized on any web project.
