css圆形镂空(优惠券背景图)的实现

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>

<!doctype html><head><meta charset="UTF-8"><title>process</title><style>body{background: gray;}.many-circles {margin: 10px 0 0 40px;width: 200px;height: 100px;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,radial-gradient(circle at left top, transparent 10px, #eeeeee 0) bottom left / 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></script></body></html>

效果如下

<style>body{background: gray;}.hollow-one-circle{display: inline-block;width: 246px;height: 218px;position: relative;background: radial-gradient(circle at 0 106px, transparent 10px, #FF4654 0) top left/246px 100% no-repeat;}.hollow-one-right{display: inline-block;width: 718px;height: 218px;position: relative;background: radial-gradient(circle at 718px 106px, transparent 10px, #ffffff 0) top left/718px 100% no-repeat;box-shadow:3px 0px 13px 0px rgba(0,0,0,0.03);}.hollow-one-circle::before {content: \'\';position: absolute;height: 100%;width:5px;top: 4px;left: 246px;background-image: linear-gradient(to bottom, #FF4654 5px, transparent 5px, transparent),radial-gradient(10px circle at 5px 10px, transparent 5px, #FF4654 5px);background-size: 5px 15px;}.hollow-one-circle:after {}</style><div data-v-85036100="" class="hollow-one-circle"></div><div data-v-85036100="" class="hollow-one-right"></div>
