您好，我似乎多年来一直在努力让右侧边栏既被卡在较大的显示器上，又在较小的显示器上脱离画布。我几乎在我的测试站点上，但我担心我无法链接到它，因为 SE 不喜欢指向网站的链接，但我有太多的代码，我很难用它来制作一个 jsfiddle。我努力了。
假设我可以接受人们可以提供的任何指示。那也将不胜感激。这是指向我的网站的链接（非 seo，因为我不使用该网站）也许可以帮助我解决我出错的地方。谢谢。 http://kompressaur.com/index.html
一切正常，直到我到达移动断点。然后出现的切换导航按钮不想做任何事情。由于我的灵魂已被摧毁，所有的帮助都值得赞赏。我花了将近 7 年的时间才走到这一步，看起来……它仍然很差。
谢谢
:(
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为移动设备定制它，而且你不需要担心你的标题大小，它会也停下来看看你的页脚。
您可以在此处阅读有关 CSS 位置粘性的信息https://www.sitepoint.com/css-position-sticky-introduction-polyfills/
所以我手头有一点时间，我想我会整理一些东西。我想我会制作整个页面，以便您可以复制并粘贴它以查看它的工作。我刚刚链接到引导程序、jquery 和stickyfill polyfill 的cdn，但你可以转到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，但有一些不同之处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自定义：

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 将侧边栏打开类切换到正文。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。然后在更大的屏幕上，您可以使用位置粘到侧边栏包装，这就是在您滚动时使其跟随的原因。然后 polyfill 会处理不支持 css 位置粘性的浏览器。
您可以在这里找到并阅读有关 polyfill 的信息https://github.com/wilddeer/stickyfill
