在Bootstrap 4的不同屏幕上最后对齐单行项目
要在Bootstrap4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-
