【问题描述】：
我正在尝试使用侧边栏的Codeply Example。
我想要一个工作滚动条到我的侧边栏。
我想要 w3schools 侧边栏中所示的侧边栏 - 我还为这个问题添加了屏幕截图。
该示例使用 Bootstrap 4.3.1。因此，任何帮助将不胜感激。我也不想妨碍 footer 的外观。我正在用我的Expected sidebar寻找任何可行的解决方案

Are you ready for Bootstap 4? It's the 4th generation of this popular responsive framework. Bootstrap 4 will include some interesting
new features such as flexbox, 5 grid sizes (now including xl), cards, `em` sizing, CSS normalization (reboot) and larger font
sizes.
