Question

我在某些文字下方的一个中间行添加了一个glyphicon。之后他们应该提供一个与帖子互动的按钮。但后来他们只是没有展示。为了测试它们是否一般不显示我在左行添加了另一个，它在哪里工作，但为什么？

代码：

<body>
    <div id="navbar">
        <nav class="navbar navbar-inverse navbar-fixed-top">
            <div class="container-fluid">
                <div class="navbar-header">
                    <a class="navbar-brand" href="#">Sample</a>
                </div>
                <ul class="nav navbar-nav">
                    <li class="active">
                        <a href="#">Home</a>
                    </li>
                    <li>
                        <a href="#">My Profile</a>
                    </li>
                    <li>
                        <a href="#">Sample Text</a>
                    </li>
                    <li>

图标中的glyphicon类名称错误。还注意到代码中没有关闭几个div标签。
