<div id="square" class="container animated">上下晃动</div>
 
 
 
/**
 * transform-origin 设置旋转元素的基点位置
 * animation-name 设置动画名称
 * animation-duration 设置动画时间
 * animation-fill-mode 设置播放后的状态
 * animation-iteration-count 设置循环播放的次数
 * transition-timing-function: cubic-bezier 贝塞尔曲线效果,它有四个值,指在X轴与Y轴的两个曲线的点,第一个点:X1 Y1;第二个点:X2 Y2
 * transform: translate3d 设置动画Z轴位移几个元素,表示只在Z轴上移动
 *
 * 需要注意:transform: translate3d 不等于 transform: translateZ
