User Interface (UI) design focuses on the visual elements users interact with — buttons, typography, color palettes, spacing, and layout. User Experience (UX) design addresses the overall experience of using a product — information architecture, user flows, task completion, and emotional response. Both disciplines work together to create digital products that are visually appealing, intuitive to use, and effective at guiding users toward their goals. Strong UI/UX design directly impacts conversion rates, engagement, and user satisfaction.
