Use the .d-*-flex class in Bootstrap to set a flexbox container on a screen size as shown below −

<div class="d-flex bg-primary">d-flex</div>
<span class="d-sm-flex bg-warning">d-sm-flex</span>
<span class="d-md-flex bg-info">d-md-flex</span>
<span class="d-lg-flex bg-success">d-lg-flex</span>

Above the flex is set for different screen sizes, for example,

d-sm-flex = Flex for Small Screen Size
d-md-flex = Flex for Medium Screen Size
d-lg-flex = Flex for Large Screen Size
d-xl-flex = Flex for Extra Large Screen Size
