在 Bootstrap 4 中拉伸不同屏幕中的弹性项目


为了在 Bootstrap 4 中拉伸不同屏幕中的弹性项目,使用 .align-self-*-stretch 类。

要在不同屏幕中拉伸,你需要使用 align-self-sm-stretch、align-self-md-stretch、align-self-lg-stretch 等。以下是小屏幕尺寸的示例——

<div class="d-flex bg-secondary" 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-stretch">C-one</div>
  <div class="p-2 border">D-one</div>
</div>

你可以尝试运行以下代码,以在不同屏幕尺寸中拉伸弹性项目——
