假设这个p id是a

        #a {
            width: 100px;
            height: 300px;
            background: radial-gradient(circle at top left,
            transparent 8px, #e6e4b7 0) top left,
            radial-gradient(circle at top right,
                    transparent 8px, #e6e4b7 0) top right,
            radial-gradient(circle at bottom right,
                    transparent 8px, #e6e4b7 0) bottom right,
            radial-gradient(circle at bottom left,
                    transparent 8px, #e6e4b7 0) bottom left;
            background-size: 50% 50%;
            background-repeat: no-repeat;
        }

具体参数自己调一下
