Reduced Motion
Reduced Motion is an accessibility setting and design mode. It removes or simplifies movement that people do not need.
prefers-reduced-motionA real example
When the system setting is on, a zooming page change becomes a short crossfade.

Use it when
Use it to help people who feel dizzy or sick from motion. This is called vestibular sensitivity. Keep needed state feedback.
Do not use it when
Never turn off all feedback. Replace movement through space with calmer signs of change.
Name used in code
prefers-reduced-motion 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 Reduced Motion to make the visual experience clear and easy to use. User context: When the system setting is on, a zooming page change becomes a short crossfade. Design concept to apply: Reduced Motion. Why it fits: Use it to help people who feel dizzy or sick from motion. This is called vestibular sensitivity. Keep needed state feedback. Do not use it when: Never turn off all feedback. Replace movement through space with calmer signs of change. 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): A formal document may still be a draft, release candidate, or final version. Check its status and browser or platform support. 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.
