Animation in Cardstack mirrors the motion and "zoom" of real-life objects.
For example, when you pick up a newspaper and hold it closer, it's as if you have zoomed into the page. When you set the newspaper aside, your eyes follow the motion.
Animation toolbox for developers
The main tool for developers is to use the embedded and isolated templates to get automatic animation between states.
Cardstack works great with the liquid-fire and ember-animated libraries.
Developers may also use regular CSS animation in order to help bring their work to life.
The Demo of the Card Folio project shows these patterns in action.
