        $(function () {
            $("ul li").mouseover(function () {//鼠标经过左侧li时
                var index = $(this).index();//给当前li声明一个index变量
                $(".right div").eq(index).show();//鼠标经过当前li的时候对应显示右侧对应索引的图片
                $(".right div").eq(index).siblings().hide();//隐藏其他li对应的图片
            })
        })
    </script>
    </body>
    </html>

在页面头部引用了百度的jQuery库，并引用了pure前端框架，并在css代码中进行了引用。Css代码：

@import url(pure.css);
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    body{
        font-family: "Microsoft YaHei UI Light";
        font-size: 16px;
        color: #666;
    }
    ul li{
        list-style: none;
    }
    a{
        color: #df5000;
        text-decoration: none;
    }
    .main{
        margin-top: 20px;
    }
    .content{
        width: 1024px;
        height: 360px;
        margin: 0 auto;
        padding: 15px;
        background-color:#dddddd;
        overflow: hidden;
        border-radius: 5px;
    }
    .content ul li{
        max-width: 100%;
        margin-right: 5px;
        padding: 5px;
        line-height: 24px;
        counter-increment:number;
        overflow: hidden;
        white-space: nowrap;
        text-overflow: ellipsis;
        transition: all 0.6s;
    }
    .content ul li::before{
        display: inline-block;
        width: 20px;
        height: 20px;
        content: counter(number);
        margin-right: 5px;
    }
    .content ul li:nth-child(1)::before{
        color: rgba(255,0,0,.9);
    }
    .content ul li:nth-child(2)::before{
        color: rgba(255,0,0,.6);
    }
    .content ul li:nth-child(3)::before{
        color: rgba(255,0,0,.4);
    }
    .content ul li:hover{
        background-color: #fff;
        border-bottom: 1px dashed #000;
        border-radius: 5px;
    }
    .content .right{
        height: 334px;
        overflow: hidden;
    }
    .content .right img{
        display: block;
        width: 100%;
        height: 334px;
    }

需要将pure.css放在和html同一目录下。以下是效果图：
