An icon is a small picture or symbol that serves as an intuitive representation of the content of a website.Because of their condensed size and versatility, icons are a simple, effective way to transmit information in an abbreviated pictorial form to the user. They can fulfil these functions far more effectively than words on the screen. Iconic images are often applied to illustrations and have become inseparable from the Flat Design trend. When an icon forms part of an interface, the most common thing to see is the use of icon fonts or scalable SVG images..
