#抽屉
抽屉从页面边缘呈现补充任务或详情，在保留原页面上下文的同时提供更大的临时工作区。

</dialog>import "@a3s-lab/ui/a3s.css";
import "@a3s-lab/ui/all";#用法
引入 CSS
导入 Tailwind 和一个完整的 A3S UI 样式包。
@import "tailwindcss";
@import "@a3s-lab/ui/a3s.css";或者只导入基本CSS、抽屉组件CSS和一个样式包。
@import "tailwindcss";
@import "@a3s-lab/ui/base.css";
@import "@a3s-lab/ui/components/drawer.css";
@import "@a3s-lab/ui/styles/a3s.css";使用CDN或批量程序导入？请参见安装页。
引入 JavaScript
复制或提供完整的 A3S UI JavaScript 包。
<script src="/assets/js/all.min.js" defer></script>或者复制或提供A3S UI运行时和抽屉脚本。
<script src="/assets/js/runtime.min.js" defer></script>
<script src="/assets/js/drawer.min.js" defer></script>使用CDN或批量程序导入？请参见安装页。
添加抽屉 HTML
A3S UI 使用原生 <dialog> 实现抽屉，让浏览器直接负责模态语义、焦点约束和背景内容的不可交互状态。抽屉脚本补充了安全的遮罩点击关闭，并等待退出动效结束后再调用原生关闭方法。该组件不模拟拖动手势、吸附点或拖动手柄。
<button type="button" class="btn" data-variant="outline" onclick="document.getElementById('demo-drawer').showModal()">打开抽屉</button>

</dialog>#HTML 结构
<button type="button" onclick="drawer.showModal()">可选- 触发按钮。A3S UI 直接使用原生
HTMLDialogElement.showModal()方法。 <dialog class="drawer" data-side="bottom|top|left|right">原生模态抽屉。省略
data-side时从底部打开；存在标题和说明时添加aria-labelledby与aria-describedby。JavaScript 会添加data-drawer-initialized标记并管理带动效的关闭过程。<article>抽屉内容表面。
<header>可选- 包含标题与可选说明的抽屉标题区。
<section>可选- 可滚动的主体内容区。
<footer>可选- 位于主体之后的操作区。
#JavaScript API
React 的 useDrawer 与 Vue 的同名 composable 暴露原生 showModal() 与增强后的 close(returnValue)。close() 会等待不超过 220ms 的退出过渡，并在减少动效环境中立即完成。
#示例
#侧面
使用data-side设置视口一侧。可用值为 top、right、bottom 和 left。
<div class="flex flex-wrap gap-2">
