用一个DIV画图通过background-image叠加实现

div {
width: 170px;
height: 140px;
background-image:
radial-gradient(circle at 50% 120%, rgba(0,0,0,0.7) 23%, rgba(0,0,0,0) 48%),
lear-gradient(30deg, rgba(0,0,0,0.4) 10%, rgba(0,0,0,0) 20%),
radial-gradient(circle at 50% 33%, #f8f6f7 32%, rgba(255,255,255,0) 32%),
radial-gradient(circle at -13% 55%, #f8f6f7 20%, rgba(255,255,255,0) 20%),
radial-gradient(circle at 113% 55%, #f8f6f7 20%, rgba(255,255,255,0) 20%),
lear-gradient(to bottom, #ef0015 20%, #b2000c 100%);
border-radius: 140px 140px 80px 80px;
}
