justify-content-sm-around : Justify content on small screen size justify-content-md-around : Justify content on medium screen size justify-content-lg-around : Justify content on large screen size
例如，让我们看看如何为中型屏幕设备对齐可调项(justify-content-md-around)-
<div class="d-flex justify-content-md-around bg-warning mb-5"> <div class="p-2 bg-danger">RANK 1</div> <div class="p-2 bg-info">RANK 2</div> <div class="p-2 bg-secondary">RANK 3</div> </div>
