CSS: alert ​

.instui-alert · stable — 一則帶有狀態色條與來自共用圖示集的遮罩狀態圖示的內嵌訊息。

自訂的 -icon-<name> 會替換狀態圖示，但保留該變體的彩色色條；色條填充在更高特異性下會被重新指定，因此共用圖示繪製器不會覆蓋它。直接的關閉按鈕預設為 small；加入大小修飾符可覆寫它。

Source: alert.css

TIP

JS 加強 — 此元件的 CSS 可獨立呈現與運作；與 @pantoken/interactions 搭配可加入互動行為。其 -timeout 修飾符由該行為驅動。參見下方的 modifier table。

無障礙 ​

對於重要訊息，新增 role="alert" 或一個 aria-live 區域以便輔助技術能夠宣告；關閉控制是一個已標示的關閉按鈕（範例中的 .instui-close-button 帶有 aria-label="Close"）。

使用方法 ​

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

範例 ​

html
<div class="instui-alert -icon-megaphone --mb-md">

  Congratulations! You're using the "success" color.
  <button class="instui-close-button" aria-label="Close"></button>

修飾器說明
.-color-danger錯誤訊息。

.-timeout-1自動關閉前一秒。

自訂屬性 ​

屬性型別預設說明

--pantoken-alert-icon-bg<color>—圖示後方的彩色狀態色條填充；每個 -color-* 變體會設定其自己的填充。
--timeout<integer>—自動關閉前的毫秒數；0 可停用。需要 alert 互動套件。
