在Bootstrap 4的不同屏幕上拉伸弹性项目
要在Bootstrap4的不同屏幕上拉伸弹性项目，请使用.align-self-*-stretch类。
要在不同的屏幕上进行展示，您需要使用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>
