我正在开发一个网站，其中我有一个网站模板，下拉菜单的宽度已满，我怎样才能将宽度减小到主标题的大小。我已经输入了显示代码页面和 html 页面中使用的 css 脚本也在下面输入。请帮助将下拉菜单的宽度减小到精确的标题框大小。

<!DOCTYPE html>
<html>

    <script src="ddmenu/ddmenu.js" type="text/javascript"></script>
    <style>
        /*The following are for this demo page only (not required for the ddmenu).*/
        body { background: #eee url(loginpage1.jpg) no-repeat center 0px; padding-top:90px;}
    </style>
</head>
<body>
<nav id="ddmenu">

  margin-bottom: 8px;
  font-size: 24px;
}

    enter code here

#ddmenu div.column h3 {text-transform:uppercase;}

/* useful when http://www.menucool.com/ddmenu/one-menu-for-all-pages */
#ddmenuLink {display:none;}

最佳答案 

#ddmenu .full-width .dropdown {
    width:40%; // give width as per your need.
    padding:0;
    margin:0;
}
