我正在使用 bootstrap 开发在线网络应用程序。导航不工作，我尝试了一些东西但没有运气。我的静态目录中存储了 bootstrap css 文件。

我的导航栏代码在下面

<!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;
}


当我点击导航栏时，我希望导航栏能按预期工作，向我显示其中的内容列表。

替换你的代码
