在Bootstrap 4中“对齐”对齐收集的项目

使用.align-content-around类在Bootstrap 4中将收集的项目“围绕”对齐。

像下面的代码片段一样设置align-content-around类-

<div class="d-flex flex-wrap align-content-around">

之后添加弹性项目-

<div class="d-flex flex-wrap align-content-around bg-primary" style="height:250">
  <div class="p-2 border">One</div>
  <div class="p-2 border">Two</div>
  <div class="p-2 border">Three</div>
  <div class="p-2 border">Four</div>
</div>

让我们看一个示例,将收集的项目对齐-
