难以设置bootstrap导航栏

我对编码非常陌生，我正在尝试用我的新网页找出一些东西。我使用了Navbar的bootstrap模板。我删除了它附带的一些链接，并按照我喜欢的方式对其进行了自定义。我的问题是当我将浏览器缩小到移动大小时，右边的切换出现，但是当我点击时没有任何反应。此外，当浏览器缩小到移动大小时，Navbar上的列表项会被推到左侧并且它们会向下堆叠。就像我说的那样，我对编码很新，而且我正在自学。这是我的代码。

<style>
    .navbar-brand {
        padding-right: 70px;
        padding-left: 0px;
    }
    .navbar-inverse {
        height: 75px;
        margin-bottom: 0px;
    }
    .nav li {
        padding-right: 30px;
        padding-top: 10px;
        font-size: 1.1em;
        font-weight: 700;
    }
</style>



<nav class="navbar navbar-inverse">
  <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" aria-expanded="false">
        <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" href="#">Brand</a></li>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class= id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Rates</a></li>
        <li><a href="#">Locations</a></li>
        <li><a href="#">Contact</a></li>
      </ul>

    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

您似乎已删除了崩溃类。

你有： <div class= id="bs-example-navbar-collapse-1">

它应该是： <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">

  

<!-- 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" aria-expanded="false">
    <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" href="#">Brand</a></li>
</div>

<!-- Collect the nav links, forms, and other content for toggling -->

<!-- collapse -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
  <ul class="nav navbar-nav">
    <li><a href="#">Home</a></li>
    <li><a href="#">Services</a></li>
    <li><a href="#">Rates</a></li>
    <li><a href="#">Locations</a></li>
    <li><a href="#">Contact</a></li>
  </ul>

</div><!-- /.navbar-collapse -->

这意味着您没有包含jQuery库或您没有正确放置它。您可以visit this link for the basic template，正如您在那里看到的那样，jQuery首先包含在bootstrap.js / bootstrap.min.js之前。此部分<div class= id="bs-example-navbar-collapse-1"> 应为 <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">，请注意，课程collapse和navbar-collapse会帮助导航条折叠。

如果您愿意，可以试试这个：

在添加自己的css

之前，将此链接添加到头部 
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

然后在body标签的末尾添加以下两个链接

<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

像这样：

<head>
    <link rel="stylesheet"  href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<style>
    .navbar-brand {
        padding-right: 70px;
        padding-left: 0px;
    }
    .navbar-inverse {
        height: 75px;
        margin-bottom: 0px;
    }
    .nav li {
        padding-right: 30px;
        padding-top: 10px;
        font-size: 1.1em;
        font-weight: 700;
    }
</style>
</head>


<body>
<nav class="navbar navbar-inverse">
  <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" aria-expanded="false">
        <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" href="#">Brand</a></li>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class= id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li><a href="#">Home</a></li>
        <li><a href="#">Services</a></li>
        <li><a href="#">Rates</a></li>
        <li><a href="#">Locations</a></li>
        <li><a href="#">Contact</a></li>
      </ul>

    </div><!-- /.navbar-collapse -->
