Bootstrap 警告和錯誤
簡介
Bootstrap 允許您為網站或 app 的成功執行、警告和錯誤信息定義樣式。在本教程中，您將學習如何做到這點。
創建一個簡單的警告信息
使用 CSS class "alert"，位於 bootstrap.css 中的行號 2123 到 2175（版本 2.0.1），您可以創建一個簡單警告信息。您可以為它添加一個可選的關閉圖標。
當您點擊警告框中的關閉圖標時，警告框關閉。要想實現這個交互效果，您必須添加兩個 JavaScript 文件 jquery.js 和 alert.js。您可以把它們添加到 body 元素關閉標簽前麵。

擴展簡單的警告信息
通過另外兩個 CSS classes "alert-block " 和 "alert-heading"，您可以擴展前麵演示的簡單的警告信息。它讓您更好地控製要顯示的文本，而且您可以在警告文本前添加文本標題。
當您點擊警告框中的關閉圖標時，警告框關閉。要想實現這個交互效果，您必須添加兩個 JavaScript 文件 jquery.js 和 alert.js。您可以把它們添加到 body 元素關閉標簽前麵。

在錯誤（error）、成功（success）、信息（information）發生時創建警告
Bootstrap 允許您在錯誤或危險、成功和信息發生時創建何時的警告。對於錯誤（error），您需要 CSS class "alert-error"。對於成功（success），您需要 "alert-success" class。對於信息（information），您需要 class "alert-info"。當然，就像前麵的實例中說明的一樣，您需要 JS 文件 jquery.js 和 alert.js。
