Skeuomorphism is the design concept of making items represented resemble their real-world counterparts. Skeuomorphism is commonly used in many design fields, including user interface (UI) and Web design, architecture, ceramics and interior design. Skeuomorphism contrasts with flat design, a simpler graphic style.
In UI and Web design, skeuomorphism attempts to create three dimensional (3-D) effects on a 2-D (flat) surface. A skeuomorphic icon on a smartphone display that represents the phone function, for example, is designed to look as much like a telephone (or handset) as is feasible, typically with shadowing, highlights and some degree of detail.
