html - Bootstrap : How to fix two overlapping content

Question

我正在尝试使用此codepen( enter link description here )创建一个网站。我遇到的问题是当我缩小窗口尺寸时，配置文件部分和主要内容部分开始重叠。我认为 codepen 在这里使用引导网格系统，所以我不太明白为什么会发生这种情况。

content overlapping image

这是代码。

任何帮助将不胜感激，因为我尝试了多种方法但没有成功。

提前谢谢您。

我看到您已向具有 profile-sidebar 类的元素添加了一个 position-fixed 类，因此无论发生什么情况，该元素都将保持固定。

您可以删除 position-fixed 类并处理 CSS 中的所有内容，使用媒体查询为较小和较大的屏幕设置其位置。
