Bootstrap4中，信息提示框功能的實現(xiàn)非常容易。而且可以使用各種類實現(xiàn)提示框的顏色、動畫等樣式。


提示框顏色：

提示框可以使用 .alert 類, 后面加上 .alert-success, .alert-info, .alert-warning, .alert-danger, .alert-primary, .alert-secondary, .alert-light 或 .alert-dark 類來實現(xiàn)顏色的變化:

提示框中在鏈接的標簽上添加 alert-link 類來設(shè)置匹配提示框顏色的鏈接：

關(guān)閉提示框

我們可以在提示框中的 div 中添加 .alert-dismissable 類，然后在關(guān)閉按鈕的鏈接上添加 class="close" 和 data-dismiss="alert" 類來設(shè)置提示框的關(guān)閉操作。

<!DOCTYPE html>

<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

<body>
<div class="container">

  <div class="alert alert-info alert-dismissable">

    <button type="button" class="close" data-dismiss="alert">&times;</button>
    <strong>淺灰色!</strong>淺灰色提示框。
  </div>
</div>
</body>
</html>

提示: × (×) 是 HTML 實體字符，來表示關(guān)閉操作，而不是字母 "x"。


提示框動畫

.fade 和 .show 類用于設(shè)置提示框在關(guān)閉時的淡出和淡入效果：
