在 Bootstrap 4 中,在不同屏幕上,将弹性项目对齐基线


在 Bootstrap 4 中,使用 .align-self-*-start 类可以在不同屏幕上将弹性元素对齐在基线上。

在不同的屏幕大小上,按以下方式设置基线 -

小屏幕

<div class="d-flex bg-primary" style="height:200px">
  <div class="p-2 border">A-one</div>
  <div class="p-2 border">B-one</div>
  <div class="p-2 border align-self-sm-baseline">C-one</div>
  <div class="p-2 border">D-one</div>
</div>

中屏幕

<div class="d-flex bg-primary" style="height:200px">
  <div class="p-2 border">A-one</div>
  <div class="p-2 border">B-one</div>
  <div class="p-2 border align-self-md-baseline">C-one</div>
  <div class="p-2 border">D-one</div>
</div>

大屏幕

<div class="d-flex bg-primary" style="height:200px">
  <div class="p-2 border">A-one</div>
  <div class="p-2 border">B-one</div>
  <div class="p-2 border align-self-lg-baseline">C-one</div>
  <div class="p-2 border">D-one</div>
</div>
