UI Design
The craft of the visual and interactive surface of a product — layout, type, color, spacing, and components users see and touch.
UI (user interface) design is the visible layer of a product: the buttons, forms, cards, typography, and color that a person actually looks at and interacts with. It turns the structure defined in UX design into a concrete, polished, on-brand surface.
Modern UI work is component-driven. Rather than designing screens one at a time, designers build reusable elements — inputs, menus, modals — inside a design system, so the interface stays consistent and ships faster as the product grows.
