Interface design (UI - User Interface ) has been around longer than the Internet we know today. In fact, the first arcade games had their interface to guide players through menus and options. Ergonomics and visuals have greatly evolved, but the goal remains the same. The interface of a website or application should be intuitive and ultimately convert the user to the desired goal. In other words, the interface allows communication between humans and your web platform. This aspect brings together components such as color, typography and shape.
