Gestalt principle

Gestalt principle of common region

Understand why elements enclosed by the same boundary are perceived as a group, even when spacing alone is ambiguous.

In one sentence

A shared boundary can turn separate elements into one perceived group.

Why it matters

Containers, cards and panels provide an explicit grouping signal. Used carefully, they make structure clear without adding explanatory text.

Applied example

Placing billing fields inside one panel and shipping fields inside another makes two form sections obvious even when the fields use identical styling.

What to remember

  • Use containers when proximity is not enough.
  • Keep each region semantically coherent.
  • Avoid wrapping every element in a card.
