Scroll Snap
CSS Scroll Snap lets a scrolling area stop at chosen alignment points after people scroll.
Another example
A touch product tour has five full-screen panels with required inline snapping. Its `scroll-padding` leaves room for the sticky header. Every panel also works by keyboard and direct link. At 280% zoom, people can still pan around large content without getting trapped.
Main parts
- 01Snap container
- 02Snap areas

Use it when
Use it when content has clear stopping points and people should still scroll in the normal browser way.
Do not use it when
Avoid strong required snapping for long articles, zoomed content, scrolling areas inside other scrollers, or free browsing.

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 Scroll Snap to make the visual experience clear and easy to use. User context: A touch product tour has five full-screen panels with required inline snapping. Its `scroll-padding` leaves room for the sticky header. Every panel also works by keyboard and direct link. At 280% zoom, people can still pan around large content without getting trapped. Design concept to apply: Scroll Snap. Why it fits: Use it when content has clear stopping points and people should still scroll in the normal browser way. Do not use it when: Avoid strong required snapping for long articles, zoomed content, scrolling areas inside other scrollers, or free browsing. 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.
