过渡动画
transition:width 500ms(执行500毫秒) ease,height 500ms ease 500ms(延迟),background-color 500ms ease 1s
变成圆角
transition:border-radius 500ms ease;
所有的一起
transition:all 500ms
设置过度的运动方式
transition-timing-function
div:nth-child(1){
transition:all 1s ease(匀速)|ease-in(开始快)|ease-out(越来越快 突然停止)|ease-in-out(开始和结束时候慢)
}
