User experience (UX) and user interface (UI) differ in their focus within design. UX encompasses the overall experience a user has when interacting with a product, emphasizing functionality, usability, and emotional satisfaction. It involves research, tests, and user feedback to create a product that meets user needs. Conversely, UI refers to the specific visual and interactive elements of a product, such as buttons and layouts. While UX ensures that the product is intuitive and user-friendly, UI focuses on the aesthetic and responsive design. Successful products require a harmonious balance between both elements.
