######优惠券的背景渐变色怎么弄啊
width:343px;
height: 78px;
background:t radial-gradient(circle at right top, transparent 6px, #fff 0) top left / 262px 51% no-repeat,
radial-gradient(circle at right bottom, transparent 6px, #fff 0) bottom left /262px 51% no-repeat,
radial-gradient(circle at left top, transparent 6px, #fff 0) top right /81px 51% no-repeat,
radial-gradient(circle at left bottom, transparent 6px, #fff 0) bottom right /81px 51% no-repeat;
这是我想要达到的效果,但是背景色的渐变色会冲突无法使用linear-gradient
