User Interface (UI)

A User Interface (UI) refers to the visual and interactive elements of software, websites, or applications with which users directly interact, such as menus, buttons, icons, and other visual components that enable navigation, interaction, and task completion in digital products.

A good UI should be user-friendly yet visually appealing to improve overall user experience; its design should focus on layout principles like color schemes, typography, and typographical conventions to produce user-friendly designs which facilitate understanding while increasing satisfaction and engagement.
