animation-name 动画名称，可以有多个值，用逗号隔开，表示绑定了多个动画

animation-name属性为动画指定一个名称

animation-name兼容主流的浏览器，不过还是需要加前缀去兼容

animation-name有两个属性值，分别是keyframename和none

animation-duration 动画持续时间默认是0

animation-timing-function 动画时间函数

animation-delay 动画延迟时间

animation-delay 属性定义动画什么时候开始，单位可以是秒（s）或毫秒（ms），允许负值，-2s使动画马上开始，但会跳过2s进入动画

animation-iteration-count 动画循环次数

animation-iteration-count: number | infinite 默认为1

animation-direction: normal | reverse | alternate | alternate-reverse 正常；反向；正反交替；反正交替

alternate 和 alternate-reverse ，如果animation-itreation-count 不是设置成 infinite ，则只会执行一次就停止

animation-fill-mode 动画延迟未执行时，或者动画执行完毕后的停留状态（动画不能设置为循环，否则无法停止）

animation-fill-mode: none | forwards | backwards | both 无结束状态开始状态看情况

animation-play-state: running | paused 动画运行状态：运行 | 暂停

animation 简写

animation: name duration timing-function delay iteration-count direction fill-mode play-state

动画性能优化：

用position-fixed代替background-attachment

带图片的元素放在伪元素中

will-change

兼容性IE13+ 感觉可以放弃了……
