Flat Web Designing
Flat design is a minimalistic design approach that emphasizes usability. It features clean, open space, crisp edges, bright colours and two-dimensional/flat illustrations.
Microsoft was one of the first to apply this design style to its interface, seen by some as a backlash against the popular skeuomorphic design that Apple kicked off with its iOS interface. Instead of converting a real-life object, such as a calendar, into a tiny realistic illustration, advocates of flat design identify apps with simple, icon-like images.
Rather than bringing aspects of real life to an interface, this illustrates a clear separation between technology and tactile objects.
Simple images convey messages more quickly than detailed illustrations. Images like icons can indicate universal actions or purposes so that everyone can easily understand them.
It's easy to see an immediate difference between a skeuomorphic and a flat design. Notice how the bigger, solid colour blocks are more attention-grabbing and the meaning of the icons can quickly be perceived.
Design is how it works.
