<style type="text/css">
.wrapper {
position: relative;

height: 100vh;
overflow: hidden;
}
.wrapper::before {
content: '';
position: absolute;
top: 0;

bottom: 0;
background: url(https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1603428298496&di=64640a01efa82d69fd270969ca2a8321&imgtype=0&src=http%3A%2F%2Fattach.bbs.miui.com%2Fforum%2F201405%2F31%2F124814kg76m5xeenbax6qn.jpg);
