First Public Working Draft: Animation Triggers

> The CSS Working Group [https://www.w3.org/groups/wg/css] has published a First Public Working Draft of Animation Triggers. It defines CSS properties and an API for creating mechanisms that affect animation playback, based on DOM events resulting from user interaction, or on entry/exit of ranges on animation timelines. In simple terms: this will let you start animations based on defined triggers, like mouse clicks or certain scroll (progress) events.
