你好，我多年来一直在努力让右侧边栏既能在较大的显示器上显示，又能在较小的显示器上脱离画布。我在我的测试网站上快到了，但我担心我无法链接到它，因为SE不喜欢链接到网站，但我有太多的代码，我很难弄清楚这一切。我试过了。
假设我可以接受人们提供的任何建议。我们也将不胜感激。这里有一个链接到我的网站（非seo，因为我不使用该网站），也许可以帮助我在哪里出错。谢谢http://kompressaur.com/index.html
在我到达移动断点之前，一切都很好。然后出现的切换导航按钮不想做任何事情。感谢所有的帮助，因为我的灵魂已经被摧毁。我花了将近7年的时间才走到这一步。。一切还是很糟糕。
感谢

所以我认为你最好的选择是实际使用css position sticky和stickyfill polyfill，因为你可以非常简单地使用css为移动设备自定义它，而且你不需要担心你的页眉大小，它也会为你的页脚停止。
你可以在这里阅读关于css位置粘性的文章https://www.sitepoint.com/css-position-sticky-introduction-polyfills/
所以我手头有一点时间，想我会做点什么。我想我会把整页都做出来，这样你就可以复制粘贴它，看看它能起作用。我刚刚链接到了bootstrap、jquery和stickyfill polyfill的cdn，但你可以直接转到url并复制它们，这样你就可以在本地服务器上运行它们。
在这里，它应该看起来与您的页面相同，但有一些差异。复制并粘贴整个页面，看看它是如何工作的，然后您可以根据自己的喜好进行定制：

At Bootply we like to build simple Bootstrap templates that utilize the code Bootstap CSS without a lot of customization. Sure you can
find a lot of Bootstrap themes and inspiration, but these templates tend to be heavy on customization.</p>

首先，我使用jquery将侧边栏的类切换为打开到正文。这将允许您在单击侧边栏切换按钮时自定义侧边栏和覆盖。然后，在较大的屏幕上，您可以使用侧边栏包装的位置粘性，这将使它在滚动时跟随。然后polyfill将处理不支持css位置粘性的浏览器。
你可以在这里找到并阅读有关polyfill的信息https://github.com/wilddeer/stickyfill
