在手机抖动/抖动上的自适应设计。常见原因？

Question

这是一个更普遍的问题。我有一个使用Bootstrap 4的站点，它在桌面上看起来很好，在移动设备上通常也很好。但是，在某些页面上，向下滚动时，从导航栏到页脚的内容会晃动或抖动。这就好像页面边界的边界太多了。所以它永远都不会停留在原地，总是依靠你的手指左右转向。我试图调试它，从字面上逐行删除违规页面及其相应的CSS。不过，它似乎仍在继续发生。我在想，也许与Bootstrap css中内置的自然边界存在某种冲突，但它应该发生在每一页上。这里包含太多的代码，所以我想知道是否有人对我可能想要保留的东西有什么一般概念。我应该注意到这个问题只发生在手机上。提前致谢。

更新：感叹。好的，这是代码。我不想这样做，因为要筛选很多东西。这是CSS。我很抱歉这么久。我很茫然。

如果你使用Git，你可以做平分，并查看被引入的误差
