UI/UX design refers to the fields of User Interface (UI) and User Experience (UX) design—key aspects of developing digital products such as websites and apps.  
UI design focuses on the look, feel, and interactivity of a product interface. UI designers create visual elements such as layout, color schemes, typography, buttons, icons, and animations, aiming to make digital interfaces aesthetically pleasing, easy to use, and consistent with a brand’s identity.
UX design addresses the user’s overall experience when interacting with a product or service. UX designers work on understanding user needs, structuring content, defining user flows, creating wireframes and prototypes, conducting testing, and refining products based on user feedback. The focus is on usability, accessibility, and satisfaction throughout the user journey
