Question

请帮忙！我的子菜单没有显示，我已经审查过，直到我的眼睛已经流血。我知道这很简单，但我没时间。这是html：

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head><title>SubMenu Nav | Auto</title>
    <meta name="description" content="."/>
    <meta name="keywords" content=""/>
    <meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
    <link href="/favicon.ico" rel="shortcut icon"/>
    <link type="text/css" rel="stylesheet" href="css/core.css"/>
    <link type="text/css" rel="stylesheet" href="css/styles.css"/>
    <link type="text/css" rel="stylesheet" href="css/nav.css"/>
</head>
<body style="text-align:center;" class="dev home">
<div class="wrapper">
    <div class="nav">
        <ul>
            <li class="first"><a href="/">Nav Item</a>
                <ul>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                </ul>
            </li>
            <li><a href="/">Nav Item</a></li>
            <li><a href="/">Nav Item</a></li>
            <li><a href="/">Nav Item</a>
                <ul>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                    <li><a href="/">Nav Sub Item</a></li>
                </ul>
            </li>
            <li><a href="/">Nav Item</a></li>
        </ul>
    </div>
    <img src="images/trailer.jpg" alt=""/></div>
</body>
</html>
