html代码：

        padding: 0;
        margin: 0;
    }

    body {
        background: #f0f0f0;
        color: #000;
    }

    div {
        width: 240px;
        height: 60px;
        padding: 70px 30px;
        cursor: pointer;
        box-shadow: 0 15px 10px #ddd;
        background: #fff;
        position: absolute;
        z-index: 10;
        top: 0;
        left: 0;
