Bootstrap 4 .d-*-flex class
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 |
