Question

我正在使用引导程序来开发在线Web应用程序。导航无法正常工作，我尝试了一些操作，但是没有运气。我在静态目录中存储了引导CSS文件。

我的导航栏代码位于以下

<!DOCTYPE html>
<html lang="en">
{%load staticfiles%}
  <head>

    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">

    <title>Maps - Map</title>

    <!-- Bootstrap core JavaScript -->
    <script src="vendor/jquery/jquery.min.js"></script>
    <script src="vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
    <!-- Bootstrap core CSS -->
    <link href="{% static '/css/bootstrap.min.css' %}" rel="stylesheet">
    <!-- Custom styles for this template -->
    <link href="{% static 'css/2-col-portfolio.css' %}" rel="stylesheet">

  </head>


  <body>

    <!-- Navigation -->
    <nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
      <div class="container">
        <a class="navbar-brand" href="{% url 'polls:home' %}">FestiMaps</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
          <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarResponsive">
          <ul class="navbar-nav ml-auto">
            <li class="nav-item active">
              <a class="nav-link" href="{% url 'polls:home' %}">Home
                <span class="sr-only">(current)</span>
              </a>
            </li>

          </ul>
        </div>
      </div>
    </nav>


<center>
<div class = "section">
<iframe></iframe>
</div>
</center>








<footer class="py-5 bg-dark">
      <div class="container">
        <center><p class="m-0 text-center text-white">Copyright &copy; Maps Creators 2019</p></center>
      </div>
      <!-- /.container -->
    </footer>


  </body>

</html>


<style class="cp-pen-styles">
body
{
  vertical-align: middle;
  background: #27ae60;
}

我希望通过单击导航栏时向我显示其中的内容列表来使导航栏按预期工作。
