html - 如何将 Bootstrap 卡片放置在另一张具有可滚动内容的卡片下方？

问题描述

我的网页有两张卡片：一张在另一张下方。顶部卡片具有包含大量输入组的可滚动正文。我希望将底部卡插入顶部卡的正下方。

我遇到的问题是底部卡片放置在页面底部很远，好像布局考虑到顶部卡片的输入组占用的空间，但这些应该隐藏在可滚动部分内。

下面的代码显示了我的设置。

干杯。

解决方案

您必须制作一些height以 px 为单位的固定大小。

例如，删除 style="height: 45%;"、替换 style="max-height: 35%; overflow-y: auto;"为style="max-height: 150px; overflow-y: auto;"

通常，您的代码非常混乱。
