此处的屏幕截图我的网站上需要一个模态，我决定在 bootstrap 网站上随意复制模态的代码。只是现在它显示非常小。

这是模态代码：

<!-- Modal (EXACT COPY FROM BOOTSTRAP) -->
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
  <div class="modal-dialog modal-dialog-centered" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

如果您想要为您的网站使用Bootstrap v4模式，它们是不言自明的。但为了举例，希望能帮助你。下面的代码适用于Bootstrap模式弹出窗口（大）：

<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
</head>

<body>

<div class="container">
  <h2>Large Modal</h2>
  <!-- Button to Open the Modal -->
  <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
    Open modal
  </button>

  <!-- The Modal -->
  <div class="modal fade" id="myModal">
    <div class="modal-dialog modal-lg">
      <div class="modal-content">
      
        <!-- Modal Header -->
        <div class="modal-header">
          <h4 class="modal-title">Modal Heading</h4>
          <button type="button" class="close" data-dismiss="modal">&times;</button>
        </div>
        
        <!-- Modal body -->
        <div class="modal-body">
          Modal body..
        </div>
        
        <!-- Modal footer -->
        <div class="modal-footer">
          <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        </div>
        
      </div>
    </div>
  </div>
  
</div>
