本文主要介绍了css圆形镂空(常用做优惠券背景图)，分享给大家，具体如下：

.hollow-compose-three-circles {
  width: 300px;
  height: 100px;
  position: relative;
  background: radial-gradient(circle at right top, transparent 10px, #00adb5 0) top left / 60px 51% no-repeat,
    radial-gradient(circle at right bottom, transparent 10px, #00adb5 0) bottom left /60px 51% no-repeat,
    radial-gradient(circle at left top, transparent 10px, #eeeeee 0) 60px 0/230px 51% no-repeat,
    radial-gradient(circle at left bottom, transparent 10px, #eeeeee 0) 60px 50px /230px 51% no-repeat,
    radial-gradient(circle at 10px 50px, transparent 10px, #eeeeee 0) 290px 0/10px 100px no-repeat;
   filter: drop-shadow(2px 2px 2px rgba(0,0,0,.2));
}
 
.hollow-compose-three-circles::after {
  content: '';
  height: 80px;
  border: 1px dashed #fff;
  position: absolute;
  left: 60px;
  top: 0;
  bottom: 0;
  margin: auto;
}
<div  class="hollow-compose-three-circles"></div>
