导致抖动的问题有很多, 具体需要看你的代码,比如:
动画重复播放
动画播放速度曲线
元素的大小发生了变化等等..

效果图:
代码:
* {margin: 0
padding: 0
}
body {
background: #ccc
}
#cloud {
width: 330px
height: 120px
background: #f2f9fe

background: -moz-linear-gradient(top, #f2f9fe 5%, #d6f0fd 100%)
background: -ms-linear-gradient(top, #f2f9fe 5%, #d6f0fd 100%)
background: -o-linear-gradient(top, #f2f9fe 5%, #d6f0fd 100%)
background: linear-gradient(top, #f2f9fe 5%, #d6f0fd 100%)
border-radius: 100px
position: relative

}
#cloud:after, #cloud:before {
