Browser support

picola targets current evergreen browsers. It relies on the Web Animations API, ResizeObserver and Pointer Events — supported by up-to-date Chrome, Edge, Firefox and Safari, including their mobile builds.

Platform APIs

API	Used for
Web Animations API	Compositor-driven open / close transitions, clip reveals and fades.
Pointer Events	Unified mouse / touch / pen gesture handling.
ResizeObserver	Recomputing fit and pan bounds when the viewport changes.

Motion & accessibility

All transitions honor prefers-reduced-motion — when the user prefers reduced motion, transitions become instant.

The viewer ships a focus trap, screen-reader live announcements of slide changes, and role="group" with aria-roledescription="slide" on each slide. Every control carries an accessible label you can localise through the labels prop.
