为什么点击链接，鼠标没反应呢

.baner ul{
            /*position: relative;*/
            list-style: none;
            margin:0px;
            margin-left: 0px;
            padding: 0px;
            background-color: #54AD0A;
            width: 540px;
            height: 30px;
            z-index: 5;
            text-align: center;

        }
        .baner li{
            float: left;
            /*margin: 2px;*/
            text-align: center;
            list-style-position: inside;
        }
        .baner a:link,a:visited{
            /*position: absolute;*/
            /*left: 380px;*/
            /*top: 20px;*/
            display: block;
            text-decoration: none;
            color: white;
            font-style: normal;
            font-size:12px;
            margin: 2px;
            padding: 2px;
             cursor: pointer;
             pointer-events: none;
             z-index: 999999;

        }
        .baner a:hover{
            font-size:14px;
        }
前面是css代码，下面是html
<div class="baner">
        <img src="01/images/logo.jpg">
        <ul>
<li>
<a href="#">网站首页</a>
</li>
<li>
<a href="#">公司新闻</a>
</li>
<li>
<a href="#">行业动态</a>
</li>
<li>
<a href="#">基地管理</a>
</li>
<li>
<a href="#">会员服务</a>
