要在小、中、大和超大屏幕尺寸上对齐弹性项目，请使用 justify-content-*-start 类。
我们先来看看小屏幕尺寸的情况 −
<div class="d-flex justify-content-sm-start bg-primary mb-5"> <div class="p-2 bg-info">Interface</div> <div class="p-2 bg-secondary">Packages</div> <div class="p-2 bg-warning">Multithreading</div> </div>
以同样的方式，针对中、大和超大屏幕尺寸实现如下 −
justify-content-md-start:中屏幕尺寸 justify-content-lg-start:大屏幕尺寸 justify-content-xl-start:超大屏幕尺寸
您可以尝试运行以下代码，在不同屏幕尺寸上对齐起始页中的弹性项目 −
