如何在纯 HTML/JS 中应用 Tailwind UI 动画

Question

我正在尝试使用示例 tailwindui.com 组件。 他们在 cmets 中定义了动画部分，但我无法弄清楚我应该如何在我的代码中使用这些动画部分。我正在使用普通的 html/js，并且不希望为此使用任何框架/lib。

我在这里尝试显示/隐藏模式对话框。 背景覆盖的动画 doe 给出为

 <!--
      Background overlay, show/hide based on modal state.

      Entering: "ease-out duration-300"
        From: "opacity-0"
        To: "opacity-100"
      Leaving: "ease-in duration-200"
        From: "opacity-100"
        To: "opacity-0"
    --> 

我不知道如何将此信息编码到背景覆盖 div。

<div id="myModal" class="hidden fixed z-10 inset-0 overflow-y-auto" aria-labelledby="modal-title" role="dialog" aria-modal="true">
  <div class="flex items-end justify-center min-h-screen pt-4 px-4 pb-20 text-center sm:block sm:p-0">
    <!--
      Background overlay, show/hide based on modal state.

      Entering: "ease-out duration-300"
        From: "opacity-0"
        To: "opacity-100"
      Leaving: "ease-in duration-200"
        From: "opacity-100"
        To: "opacity-0"
    -->
    <div class="fixed inset-0 bg-gray-500 bg-opacity-75 transition-opacity" aria-hidden="true"></div>

这是我迄今为止尝试过的；

<style>
  .modalEntry {animation:modal-in 1s;}  
  .modalExit {animation:modal-in 1s;}

@keyframes modal-in {
    from {opacity-0;}
    to {opacity-100;}
}
@keyframes modal-out {
    from {opacity-100;}
    to {opacity-0;}
}
</style>

<button class="border border-red-500" onclick="toggleModal()">Toggle modal</button>

<!-- This example requires Tailwind CSS v2.0+ -->
<div id="myModal" class="hidden fixed z-10 inset-0 overflow-y-auto" aria-labelledby="modal-title" role="dialog" aria-modal="true">
  <div class="flex items-end justify-center min-h-screen pt-4 px-4 pb-20 text-center sm:block sm:p-0">

您不能使用“隐藏”类制作动画，因为 css 属性 display 不可动画。

动画类型 - 不可动画documentation

但是，要解决这个问题，您可以使用setTimeout 函数，它将帮助我们延迟切换类并避免动画/过渡中断。还需要创建两个类来覆盖初始类并使用 javascript 添加或删除它们。

#myModal.modalEntry {
  opacity: 1;
}
#box.animate {
  opacity: 1;
  transform: translateY(0) scale(1);
  transition: all 0.2s ease-in;
}

#myModal.modalEntry {
  opacity: 1;
}

#box.animate {
  opacity: 1;
  transform: translateY(0) scale(1);
  transition: all 0.2s ease-in;
}
