Bootstrap 4 .justify-content-* 类


要对齐弹性项目,请使用 justify-content-* 类。

使用以下任意一个来对齐弹性项目,使其处于开始、结束、周围和中间。

justify-content-start – Align Flex items at the start
justify-content-end  - Align Flex items at the end
justify-content-around – Align  flex items around on different screen sizes
justify-content-between  - Alex flex items in between on difference screen sizes

我们来看一个示例,将弹性项目设置在开始 −

<div class="d-flex justify-content-start bg-primary mb-5">
  <div class="p-2 bg-danger">RANK 1</div>
  <div class="p-2 bg-secondary">RANK 2</div>
  <div class="p-2 bg-warning">RANK3</div>
</div>

以下是实现 justify-content-* 类的示例 −
