UI and UX are related but distinct disciplines, often confused because they're so closely intertwined in practice.
UI: How It Looks and Feels
User Interface design focuses on the visual and interactive elements — colors, typography, buttons, spacing — the tangible surface a user directly interacts with.
UX: How It Works for the User
User Experience design is the broader discipline of how a product functions for real people — the flow, the logic, whether a task is actually easy to complete, independent of visual polish.
Why Both Matter
A beautifully designed interface (great UI) can still be confusing and frustrating to actually use (poor UX) — genuinely good design requires both working together.
