在Bootstrap中的特定屏幕尺寸上水平显示弹性项目
要在不同的屏幕尺寸中水平设置弹性项目，请使用flex-*-row类。
各种屏幕尺寸均设置为小，中，大和特大屏幕尺寸。让我们看看如何在较小的屏幕尺寸下将弹性项目水平对齐-
<h2>Flex Row (Small Screen)</h2> <div class="d-sm-flex flex-sm-row bg-primary mb-3"> <div class="p-2 bg-primary">Audi</div> <div class="p-2 bg-warning">BMW</div> <div class="p-2 bg-secondary">Benz</div> </div>
以下是在不同屏幕尺寸上水平显示弹性项目的示例-
