Bootstrap 4 .flex-wrap-reverse类

在Bootstrap 4中使用flex-wrap-reverse类来包装flex项目并以相反的顺序进行包装。

这是flex-wrap和flex-wrap-reverse之间的区别-

如以下代码片段所示设置wrap-flex-reverse-

<div class="d-flex flex-wrap-reverse bg-primary">
  <div class="p-2 border">Rank 1</div>
  <div class="p-2 border">Rank 2</div>
  <div class="p-2 border">Rank 3</div>
  <div class="p-2 border">Rank 4</div>
  <div class="p-2 border">Rank 5</div>
<div>

您可以尝试运行以下代码以实现flex-wrap-reverse类-
