CSS: alert ​

.instui-alert · 稳定 — 带有状态色条和来自共享图标集合的遮罩状态图标的内联消息。

自定义 -icon-<name> 会替换状态图标，但保留该变体的彩色条；条的填充在更高优先级处被重新应用，以防共享图标绘制器覆盖它。直接的关闭按钮默认为小号；添加大小修饰符以覆盖它。

Source: alert.css

TIP

JS 增强 — 该组件的 CSS 可单独渲染并工作；将其与 @pantoken/interactions 配对以添加交互行为。其 -timeout 修饰符由该行为驱动。见下方的 modifier table。

无障碍 ​

对于重要消息，添加 role="alert" 或一个 aria-live 区域以便辅助技术进行公告；可关闭控件为带标签的关闭按钮（示例中的 .instui-close-button 携带 aria-label="Close"）。

用法 ​

css
@import "@pantoken/components/components.css";
@import "@pantoken/components/alert.css";

示例 ​

html
<div class="instui-alert -icon-megaphone --mb-md">
  An alert with the default <code>info</code> color, and a custom icon.
</div>
<div class="instui-alert -color-success">
  Congratulations! You're using the "success" color.
  <button class="instui-close-button" aria-label="Close"></button>
</div>
