Question

我试图像在互联网上提供的示例中那样打开和关闭一个模式，但似乎我无法切换（它始终处于打开状态）并且我什至无法关闭它：

模式

<body>
    <div class="container">

        <button class="btn btn-primary" data-target="#campModal" data-toggle="modal"></button>

        <div class="modal" id="campModal" tabindex="-1">
            <div class="modal-dialog">
                <div class="modal-content">

一旦包含必需的依赖项，您的代码就会起作用。在Google Chrome开发人员工具（或Firefox）上查看控制台输出通常会有助于查找缺少的依赖项。

.btn {
  position: absolute;
  /* Center the button */
  left: 50%;
  top: 50%;
  transform: translate(-50%, -50%);
}
