全部关闭后，Bootstrap手风琴头更小

问题描述 投票：1回答：2

目前试图让一个手风琴项目在Bootstrap中工作一切都很好，直到我试图关闭所有的手风琴菜单。突然之间，当一个没有折叠时，标题要小得多。

When it is opened当它被打开时

你必须在qazxsw poi中使用一个列（qazxsw poi）来解决这个问题。只需将.col-12放入一个新的.row元素，使用类.accordion，如下所示：

<div>

在网格布局中，内容必须放在列中，只有列可以是行的直接子项。 来源：.col-12

row

这个.row给你带来了麻烦。如果你没有任何display: flex flex-wrap: wrap; margin-right: -15px; margin-left: -15px; init，你也不需要任何负边距。
