最近项目需要，需要写一些动画效果，然后对 animation 的知识巩固了一下。
animation
animation-name 需要绑定到选择器的 keyframe 名称
animation-duration 完成动画所需要的时间
animation-delay 设置延长时间
animation-timing-function 动画的运动速度
linear 动画从头到尾的速度是相同的。ease 默认。动画以低速开始，然后加快，在结束前变慢。ease-in 动画以低速开始。ease-out 动画以低速结束。ease-in-out 动画以低速开始和结束。cubic-bezier(n,n,n,n) 在 cubic-bezier 函数中自己的值。可能的值是从 0 到 1 的数值。
animation-iteration-count 动画播放的次数
infinite 规定动画应该无限次播放。
animation-direction 轮流反向播放动画
normal 默认值。动画应该正常播放。alternate 动画应该轮流反向播放。
— 好吧 这个就介绍到这里吧 如果还有什么疑问可以自己去了解一下
