Use it when

Use spacing to show which items belong together before you add borders or boxes.

Do not use it when

Never give every item the same gap. Equal gaps make the items look equally related.

Before you ship

Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.

Outcome: Use or define Spacing to make the visual experience clear and easy to use. User context: A label sits close to its input. A larger space separates one form section from the next. Design concept to apply: Spacing. Why it fits: Use spacing to show which items belong together before you add borders or boxes. Do not use it when: Never give every item the same gap. Equal gaps make the items look equally related. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.

Release checks: Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
