Twitter bootstrap 引导静态导航栏滚动

我正在尝试创建我的第一个引导站点。让我困惑的是，为什么静态导航栏不能随页面滚动。这是密码。我将包括整个标题，以防下面的jumbotron正在做我看不到的事情

<header>
        <nav class="navbar navbar-default navbar-static-top" id="site-nav" role="navigation">
            <div class="container">
                <!-- Brand and toggle get grouped for better mobile display -->
                <div class="navbar-header">
                    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                        <span class="sr-only">Toggle navigation</span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                        <span class="icon-bar"></span>
                    </button>
                    <a class="navbar-brand" id="site-brand" href="#">Josef Roy Advincula</a>
                </div>

                <!-- Collect the nav links, forms, and other content for toggling -->
                <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                    <ul class="nav navbar-nav">
                        <li><a href="#about-me" class="jlinks"><span class="glyphicon glyphicon-user"></span>About Me</a></li>
                        <li><a href="#" class="jlinks"><span class="glyphicon glyphicon-paperclip"></span>Portfolio</a></li>
                        <li><a href="#" class="jlinks"><span class="glyphicon glyphicon-phone"></span>Contact Me</a></li>
                    </ul>
                </div><!-- /.navbar-collapse -->
            </div><!-- /.container-fluid -->
        </nav>

        <div class="jumbotron">
            <div class="container">
                <img src="img/profile_pic.jpg" class="img-responsive img-circle" alt="Josef Roy Advincula"/>
                <hgroup>
                    <h1 class="text-center jumbo-header">Hi! I'm Josef</h1>
                    <h2 class="text-center jumbo-header">{ Web Developer/Programmer }</h2>
                </hgroup>
            </div>
        </div>
    </header>

切换导航

对不起，我误解了文档。通过使用修复了此问题

<nav role="navigation" class="navbar navbar-default navbar-fixed-top">

别难过，有时候，像我一样用谷歌搜索结果要比翻阅文档快得多。
