The User Interface (UI) is the component that the user interacts with when using a digital product, namely the visual and interactive part of an application. The UI Designer's work therefore focuses on visual and graphic elements, to create functional and aesthetically pleasing products. In detail, to achieve an effective and captivating result, the UI must take into account typography, color palette, animations, and all the images and entities that are part of the software screens, in addition to the user flow within the system.
