.xuanzhuan{animation:xz 1s linear infinite }@keyframes xz{
from {transform:rotate(0deg)}

}infinite 旋转不限次数，也可以改成1，旋转一次
具体css代码如下:$width: 64px
$height: 64px
$dotWidth: 10px
$dotHeight: 10px
$radius: 5px
$offset: 9.37px
@function getLeft( $x ) {
@return ($width/4)*$x
}
@function getTop( $y ) {
@return ($height/4)*$y
}
@keyframes changeOpacity {
from { opacity: 1}
to { opacity: .2}
}

代码使用scss定义了大圆和小圆圈的半径，不管改成多大只需要更改变量，下面样式无需改变。
这是CSS3里面的属性,以中心为圆点旋转:transform-origin:center 0px
旋转角度:transform:rotate(360deg)
顺时针旋转角度
旋转角度可以写在js代码里,点击旋转或者加载页面旋转.都行
