建一个style.css文件

ul,li{ padding: 0;margin: 0; list-style: none;}
    .adver{ margin: 0 auto; width: 700px; overflow: hidden; height: 454px; position: relative; background: url("../img/adver01.jpg");}
    ul{ position: absolute; bottom:10px; z-index: 100; width: 100%; text-align: center;}
    ul li{ display: inline-block; font-size: 10px; line-height: 20px; font-family: "微软雅黑"; margin: 0 1px; width: 20px; height: 20px; border-radius: 50%; background: #333333; text-align: center; color: #ffffff;}
    .arrowLeft,.arrowRight{ 
        position: absolute;
        width: 30px;
        background:rgba(0,0,0,0.2);
        height: 50px;
        line-height: 50px;
        text-align: center;
        top:200px;
        z-index: 150;
        font-family: "微软雅黑";
        font-size: 28px;
        font-weight: bold;
        cursor: pointer;
        
    }
    .arrowLeft{ left: 10px;}
    .arrowRight{ right: 10px;}
    li:nth-of-type(1){ 
        background: orange;
    }
