User Interface (UI) refers to the visual and interactive elements of a product, website, or application that users interact with. It includes graphical components such as buttons, menus, forms, icons, and layout design that facilitate user interaction and navigation.
UI design focuses on creating an intuitive and visually appealing interface that enhances the overall user experience. It considers factors like typography, color schemes, responsive design, and user feedback.
UI and UX design are closely related, with UI serving as the user's point of interaction with the overall user experience.
