本效果用css3的animation实现动画
定义和用法
animation 属性是一个简写属性，用于设置六个动画属性：
animation-name
animation-duration
animation-timing-function
animation-delay
animation-iteration-count
animation-direction
注释：请始终规定 animation-duration 属性，否则时长为 0，就不会播放动画了。
默认值： none 0 ease 0 1 normal
继承性： no
版本： CSS3
JavaScript 语法： object.style.animation="movehovertree 5s infinite"
语法
animation: name duration timing-function delay iteration-count direction;
animation-name 规定需要绑定到选择器的 keyframe 名称。。
animation-duration 规定完成动画所花费的时间，以秒或毫秒计。
animation-timing-function 规定动画的速度曲线。
animation-delay 规定在动画开始之前的延迟。
animation-iteration-count 规定动画应该播放的次数。
animation-direction 规定是否应该轮流反向播放动画。
