    首先，先在<style>下面添加 * {list-style-type: none;} 去除二级栏目的项目符号；

    其次，就是

    https://img1.mukewang.com/5c370e180001dedd10500227.jpg

    这个<a>标签 被写成了 < a>  ；

    最后是添加  

    body { margin:0; padding: 0;}

    #nav {width:1150px; margin: 0 auto;}（id的命名方式）

    .nav-menu li {width: 146px;text-align: center;}

    .drop-menu li {text-align: center;} （我总觉得你的二级栏目好乱啊）

    /*--width: 200px;*/  注释掉 (不晓得有啥用 )

    实在是找不到你的样式在哪！！！

    https://img.mukewang.com/5c371cfb000101ec05300331.jpg

     你自己找到这padding-left: 40px; 删掉就好了。

    如果你也不知道在那，那就加一个 margin:0; 在   .nav-menu > li:hover ul  下面
