Paged content with active focus — testimonials, hero slides, onboarding step cards. One item is the focus, others peripheral. Snap-to-page, often with dots/arrows. Desktop nav buttons always-visible for primary content, hover-only for secondary.

Not for navigation lists where users need to compare items (they can’t see two at once), curated browsing (use a horizontal scroll row), or showing all options at once (use a grid).

Autoplay when each slide requires reading (testimonials, feature explainers) — breaks comprehension.
