法律研究在 Bootstrap 4 的不同屏幕中从开始对齐收集的项目
要想在不同屏幕中从开始对齐收集的项目，请使用“align-content-*-start”类。
按如下所示在不同的屏幕尺寸中对齐项目 −
中等屏幕尺寸
<div class="d-flex flex-wrap align-content-md-start bg-primary" style="height:250px"> <div class="p-2 border">Work 1</div> <div class="p-2 border">Work 2</div> <div class="p-2 border">Work 3</div> <div class="p-2 border">Work 4</div> <div class="p-2 border">Work 5</div> </div>
大屏幕尺寸
<div class="d-flex flex-wrap align-content-lg-start bg-primary" style="height:250px"> <div class="p-2 border">Work 1</div> <div class="p-2 border">Work 2</div> <div class="p-2 border">Work 3</div> <div class="p-2 border">Work 4</div> <div class="p-2 border">Work 5</div> </div>
你可以尝试运行以下代码，为 Bootstrap 4 中不同屏幕尺寸的 align-content-*start 类实现对齐功能 −
