这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

AnimationTimeline 接口在 Web 动画 API represents the timeline of an animation. This interface exists to define timeline features (inherited by DocumentTimeline and future timeline types) and is not itself directly used by developers. Anywhere you see AnimationTimeline , you should use DocumentTimeline or any other timeline type instead.

特性
