自定义模式对话框
虽然 htmx 非常适合使用 CSS 框架（如 Bootstrap 和 UIKit ）内置的对话框，但 htmx 还可以轻松从头开始构建模式对话框。下面是构建模式对话框的一种方法的简单示例。
高级用法
我们将创建一个按钮，用于从服务器加载远程内容，然后在模态对话框中显示它。模态内容将添加到 <body> 元素末尾名为 #modal 的 div 中。
在这个演示中，我们将在 CSS 中定义一些漂亮的动画，然后在用户完成后使用一些Hyperscript 从 DOM 中删除模式。Hyperscript 不是 htmx 的必需项，但两者设计为一起使用，并且它比 JavaScript 更适合编写异步和面向事件的代码，这就是我们为这个示例选择它的原因。
主页 HTML
<button class="btn primary" hx-get="/modal" hx-target="body" hx-swap="beforeend">Open a Modal</button>
模态 HTML 片段
<div id="modal" _="on closeModal add .closing then wait for animationend then remove me">
<div class="modal-underlay" _="on click trigger closeModal"></div>
<div class="modal-content">
<h1>Modal Dialog</h1>
This is the modal content.
You can put anything here, like text, or a form, or an image.
<br>
<br>
<button class="btn danger" _="on click trigger closeModal">Close</button>
</div>
</div>
