## 警報佈局和行為

### 全寬警報

使用 `w-full` 實用程式類別使**警報**跨越其容器的整個寬度。這適用於所有顏色和款式變體。

僅 CSS，無需 JavaScript。 WCAG AA 可存取且與框架無關 - 可與 Django、HTMX、Laravel、React 和任何堆疊配合使用。

```html
<div role="alert" class="alert w-full">
    <span>You have 99+ new notifications.</span>
</div>
<div role="alert" class="alert alert-primary w-full">
    <span>New version of UI update is available.</span>
</div>
<div role="alert" class="alert alert-secondary w-full">
    <span>Trial period active: 14 days remaining.</span>
</div>
<div role="alert" class="alert alert-accent w-full">
    <span>Your subscription will renew in 3 days.</span>
</div>
<div role="alert" class="alert alert-info w-full">
    <span>Note: All components are WCAG compliant.</span>
</div>
<div role="alert" class="alert alert-success w-full">
    <span>Success: Frutjam UI installed successfully.</span>
</div>
<div role="alert" class="alert alert-warning w-full">
    <span>Warning: Invalid email address. Please Retry.</span>
</div>
<div role="alert" class="alert alert-error w-full">
    <span>Error: Your session has expired. Log in again.</span>
</div>
<div role="alert" class="alert alert-neutral w-full">
    <span>Profile 80% complete. Add a photo to finish.</span>
</div>
```

### 響應式警報堆疊

此警報在行動裝置上垂直堆疊，並在桌面上水平擴展，以實現最佳的螢幕使用。

```html
<div role="alert" class="alert alert-vertical sm:alert-horizontal">
  <svg xmlns="http://www.w3.org/2000/svg" width="18" height="18" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><circle cx="12" cy="12" r="10"/><path d="M12 16v-4"/><path d="M12 8h.01"/></svg>
  <span>Add a profile photo to reach 100%.</span>
  <div class="space-x-1.5">
    <button class="btn btn-sm">Skip</button>
    <button class="btn btn-sm btn-primary">Upload</button>
  </div>
</div>
```

### 內容豐富的提醒

```html
<div role="alert" class="alert alert-vertical sm:alert-horizontal w-full">
  <svg xmlns="http://www.w3.org/2000/svg" width="22" height="22" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><path d="m22 7-8.991 5.727a2 2 0 0 1-2.009 0L2 7"/><rect x="2" y="4" width="20" height="16" rx="2"/></svg>
  <div>
    <h3 class="font-bold">New Emails!</h3>
    <div class="text-xs">You have 4 unread emails</div>
  </div>
  <button class="btn btn-sm">View</button>
</div>
```
