Animation in EPUB 3

Stewart Haines

22 Sep, 2025

This sample reflowable EPUB 3 file includes some CSS animation of an SVG element, but also a Reading System script that loads and plays a Lottie animation from a json file.

It validates as EPUB 3, but will only be animated as designed in a Reading System that supports scripted chapter content. Like Apple's Books app, or Cantook or Lis-a.
