首先,先在<style>下面添加 * {list-style-type: none;} 去除二級欄目的項目符號;
其次,就是
這個<a>標簽 被寫成了 < 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;} (我總覺得你的二級欄目好亂?。?/p>
/*--width: 200px;*/ ?注釋掉 (不曉得有啥用 )
實在是找不到你的樣式在哪?。?!
?你自己找到這padding-left: 40px; 刪掉就好了。
如果你也不知道在那,那就加一個 margin:0; 在 ? .nav-menu > li:hover ul ?下面 ? ? ? ?
