User Interface (UI)

What is User Interface (UI)?

UI design defines the look and feel of screens: components, spacing, states, and brand expression—implemented in design systems for consistency.

Example: A cohesive button style (size, radius, hover) across the site reduces cognitive load compared to mismatched styles page to page.

Why User Interface (UI) matters

UI matters because visual consistency and component quality reduce cognitive load; sloppy interfaces signal unreliability even when the underlying offer is strong.

Use a component library, document tokens, and pair UI with accessible contrast and focus states.
