在Bootstrap 4的不同屏幕上最后对齐单行项目

要在Bootstrap 4的不同屏幕上最后对齐单行项目，请使用.align-items-*-end类。

在不同的屏幕尺寸上对齐-

中等屏幕尺寸

<div class="d-flex flex-wrap align-items-end bg-primary" style="height:200px">
  <div class="p-2 border">Product 1</div>
  <div class="p-2 border">Product 2</div>
  <div class="p-2 border">Product 3</div>
  <div class="p-2 border">Product 4</div>
</div>

大屏幕尺寸

<div class="d-flex flex-wrap align-items-lg-end bg-info" style="height:200px">
  <div class="p-2 border">Product 1</div>
  <div class="p-2 border">Product 2</div>
  <div class="p-2 border">Product 3</div>
  <div class="p-2 border">Product 4</div>
</div>

您可以尝试运行以下代码，以在特定屏幕尺寸的末尾对齐单行项目-
