Using ::view-transition to give the impression of animation between pages. See What's new in view transitions? (Google I/O 2024 update) for more information.

For this demonstration just click/tap any of the three images above to take you to a new page showing more information about the particular dinosaur.

Once on the new page just click/tap the 'Back to dinosaurs' link to return to this page with a reverse animation.

All this is done using fairly simple CSS styles. See view-trans.css and common.css.
