Bootstrap 4 .flex-*-column-reverse 类
使用 flex-*-column-reverse 类在不同屏幕尺寸下垂直反向显示弹性项目。
以下是使用 “flex-md-column-reverse” 类在中等大小设备上反转弹性项目的一个示例 −
<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>
同样,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>
