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>

background: radial-gradient(circle at right, transparent 10px, #00adb5 0) top right / 51% 60px no-repeat,
radial-gradient(circle at left, transparent 10px, #00adb5 0) top left / 51% 60px no-repeat;
/*radial-gradient(circle at top right, transparent 10px, #eeeeee 0) bottom right / 51% 40px no-repeat,

filter: drop-shadow(2px 2px 2px rgba(0,0,0,.2));
}
</style>
</head>
<body>
<div data-v-85036100="" class="many-circles"></div>
<script>

效果如下
<style>
body{

}
.hollow-one-circle{
display: inline-block;
