CSS双色虚线边框，京东订单界面收货地址的下划线

实现京东订单类似的下划线

.bottom_line {
		height: 10upx;
		background-image: linear-gradient(-45deg,
				#7ba9ff 0,
				#7ba9ff 10px,
				transparent 10px,
				transparent 15px,
				#ff7967 15px,
				#ff7967 25px,
				transparent 25px,
				transparent 30px);
		background-size: 40px 4upx;
		background-repeat: repeat-x;
		background-position: left bottom;
	}

 切记切记，一定要给高度和宽度！！！
