<div class="wrapper">
    <div class="circle right-circle">
      <div class="right" style="transform: rotate(-160deg);"></div>
    </div>
    <div class="circle left-circle">
      <div class="left" style="transform: rotate(-180deg);"></div>
    </div>
</div>
</body>
</html>

原理:

弄一个外部div包裹着,里面有两个二级div,都是只显示一般,左边的只显示左半部,右边的只显示右半部,二级div下都有一个作为旋转的div,他们也是只显示一般,但是和其父级div的方向刚好相反,然后通过旋转来显示出来,当第一个三级div旋转完之后,第二个三级div旋转,直至填满圈圈
