在Bootstrap中包装flex项目
如果要将弹性项目包装在Bootstrap中，请使用flex-wrap类。要包装，请使用-
<div class="d-flex flex-wrap>
然后添加要包装在其中的flex项目-
<div class="d-flex flex-wrap> <div class="p-2 border">India</div> <div class="p-2 border">US</div> <div class="p-2 border">UK</div> <div class="p-2 border">Australia</div> <div class="p-2 border">Denmark</div> </div>
您可以尝试运行以下代码，以避免包装弹性项目-
