animation-trigger
An experimental property that allows you to define exactly when an animation should start playing based on conditions like visibility in the viewport. It's part of the effort to make scroll and view-driven effects more declarative.
It is documented as part of the CSS Animations specification. This is an experimental technology. The syntax and behavior are still subject to change.
