这是一个更普遍的问题。我有一个使用Bootstrap 4的网站，它在桌面上看起来很好，在移动设备上也很好。但是，在某些页面上，当您向下滚动时，从导航栏到页脚的内容会摇摆或抖动。就像页面边界两边有太多边距一样。所以它永远不会完全固定到位，根据你的手指的不同，左右转向。我试图调试它，逐字逐句地删除违规页面及其相应的CSS。不过，它似乎仍在继续发生。我想也许与Bootstrap css中内置的自然边缘存在某种冲突，但它应该发生在每一页上。这里包含的代码太多了，所以我想知道是否有人对我可能想要保留的东西有任何一般性的想法。我应该注意到这个问题只发生在移动设备上。提前谢谢。
更新：叹息。好的，这是代码。我不想这样做，因为要筛选很多东西。这是CSS。我为此感到抱歉。我不知所措。
