示例:

</head>
<body>
<!-- Modal Trigger Button -->
<button type="button" class="btn btn-success" data-toggle="modal"
data-target="#practiseModal">
OPEN PRACTISE MODAL
</button>
<!-- Modal Body -->
<div class="modal fade" id="practiseModal" tabindex="-1" role="dialog"
aria-labelledby="practiseModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="practiseModalLabel">
Title of the Modal</h5>
<button type="button" class="close"
data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
Content of the Modal
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger"
data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</body>
</html>
输出:
滚动内容的长度超过视口：
当模态中的内容超过用户的视口时，模态变得可滚动，并且它们的滚动与页面的滚动无关。源代码和上面一样。
输出:
垂直居中的模态：
要使模态垂直居中，你应该在有’modal-dialog’类的div上添加一个’modal-dialog-centered’类。

不同尺寸的模型：
你可以为你的模版使用不同的尺寸。在具有’modal-dialog’类的div中添加以下类之一。下面是一个表格，描述了Bootstrap提供的不同尺寸。你也可以使用JS或CSS自定义尺寸。
| 尺寸 | 等级 | 宽度 (px) |
|---|---|---|
| 小型 | .modal-sm | 300 |
| 默认 | 无 | 500 |
| 大 | .modal-lg | 800 |
| 特大号 | .modal-xl | 1140 |
