Question

我正在关注Bootstrap的视频教程。但是，我的bootstrap导航栏会扩展并显示在网站徽标旁边的移动设备（窄屏幕）中。相关图片：

1 - Narrow screen view with menu expanded

在大多数普通网站上，它应该出现在徽标下面。

2 - Example of a Bootstrap website that has the correctly working mobile menu

这是我的代码

@import url(https://fonts.googleapis.com/css?family=Share+Tech+Mono);

body {
    font-family: 'Share Tech Mono', monospace;
    background-color: #fff;
}

.navbar {
    padding-top: 30px;    
    font-size: 26px;
    font-size-adjust: auto;
    background-color: antiquewhite;
}

.navbar-nav > li {
    padding-left: 15px;
}

.icon-bar {
    background-color: #000;
}

.row {
    padding: 10px;
}

                <button class="navbar-toggle" data-toggle="collapse" data-target=".navHeaderCollapse">
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>

                <div class="collapse navbar-collapse navHeaderCollapse">
                    <ul class="nav navbar-nav navbar-right">
                        <li><a href="#">Blog</a></li>
                        <li><a href="#">Contact</a></li>
                    </ul>
                </div>
            </div>
        </div>
        
        <!-- Main section of homepage -->
        <div class="container-fluid">
            <div class="row"></div> <div class="row"></div> <div class="row"></div>
            <div class="row"></div> <div class="row"></div>
        </div>
        
        <script src="js/jquery-1.12.1.min.js"></script>
        <script src="js/bootstrap.min.js"></script>
    </body>
</html>

有人可以帮忙解决这个问题吗？

你已经忘记了组合品牌和按钮的包装：

<div class="navbar-header">
   <button class="navbar-toggle" data-toggle="collapse" data-target="#navHeaderCollapse">
     <span class="icon-bar"></span>
     <span class="icon-bar"></span>
     <span class="icon-bar"></span>
   </button>
   <a class="navbar-brand" href="">My Logo</a>
</div>
