Bootstrap 4 .flex-*-column-reverse 类


使用 flex-*-column-reverse 类可将弹性项目垂直显示并在不同的屏幕尺寸上显示逆序。

以下是在中等设备上使用 “flex-md-column-reverse” 类来反转弹性项目的示例 −

<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>

以同样的方式,使用 “flex-lg-column-reverse” 类为大型设备设置 −

<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>
