Marquee
A strip of repeated content that keeps moving. It must offer controls or a still version for people who are sensitive to motion.
A real example
A festival page moves a short sponsor list slowly. It pauses on hover or focus and becomes a still, wrapped list under reduced motion.

Use it when
Use it only for short, repeated content that is not essential. The motion may add mood but must not block reading.
Do not use it when
Never use it for instructions, long text, urgent messages, or words people must chase to read.

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 Marquee to make the visual experience clear and easy to use. User context: A festival page moves a short sponsor list slowly. It pauses on hover or focus and becomes a still, wrapped list under reduced motion. Design concept to apply: Marquee. Why it fits: Use it only for short, repeated content that is not essential. The motion may add mood but must not block reading. Do not use it when: Never use it for instructions, long text, urgent messages, or words people must chase to read. 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): This is not a normative standard. Its name, limits, and expected behavior can change from one source to another. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.
