要水平显示弹性项目，请使用flex-row类。
将其添加到<div>类-
<div class="d-flex flex-row bg-primary mb-3">
现在相应地添加弹性项目-
<div class="d-flex flex-row bg-primary mb-3"> <div class="p-2 bg-info">TCS</div> <div class="p-2 bg-secondary">Wipro</div> <div class="p-2 bg-danger">Accenture</div> <div class="p-2 bg-warning">Gartner</div> </div>
这是水平实施弹性项目的完整示例-
