带有Bg-primary类的Style Bootstrap 4卡
使用Bootstrap4中的bg-primary类将重要内容添加到卡中并设置蓝色背景色。
按照以下代码片段的样式设置Bootstrap4卡-
<div class="card bg-primary text-white"> <div class="card-body">Medical Books</div> </div>
我已经在card-body类中设置了卡的主体-
<div class="card-body"> Medical Books </div>
要在Bootstarp4中实现bg-primary类，可以尝试运行以下代码-
示例
