UX (User Experience) and UI (User Interface) are critical components of design in digital products. UX focuses on enhancing overall user satisfaction by improving usability, accessibility, and the overall experience during interaction. UI, on the other hand, deals with the visual and interactive elements, such as buttons, icons, and layouts, aiming to create an aesthetically pleasing and user-friendly interface. Both UX and UI collaborate to create a seamless and enjoyable user journey in applications and websites.
