Bootstrap 4 .flex-*-column-reverse 類


使用 flex-*-column-reverse 類可將彈性專案垂直顯示並在不同的螢幕尺寸上顯示逆序。

以下是在中等裝置上使用 “flex-md-column-reverse” 類來反轉彈性專案的示例 −

<div class="d-flex flex-md-column-reverse mb-3">
  <div class="p-2 bg-warning">One</div>
  <div class="p-2 bg-danger">Two</div>
  <div class="p-2 bg-secondary">Three</div>
</div>

以同樣的方式,使用 “flex-lg-column-reverse” 類為大型裝置設定 −

<div class="d-flex flex-lg-column-reverse mb-3">
  <div class="p-2 bg-warning">One</div>
  <div class="p-2 bg-danger">Two</div>
  <div class="p-2 bg-secondary">Three</div>
</div>
