Trasition 提供了从一种状态过渡到另一种状态的改变。

Animation 则可以从不同关键帧上设置多个过渡点。

这是由五个关键帧(状态)组成的动画，两个关键帧之间的过渡效果就是一个Trasition。
整个动画的全过程，就是一个Animation。

所以：transition是Animation的一个子集，即一个Animation是由多个transition组合而成的。

animation缺点：在极端情况下，animation比transition更占资源，在前端压力过大时animation的关键帧动画无法显示出来
animation优点：在于能够实现更复杂动画

transition优点：占用资源小
transition缺点：无法实现复杂动画
