固定引导边栏

Question

我已经采取了两个div，说“Panel1”和“Panel2”，其中Panel1具有属性附加（用HTML进行硬编码，因此必须强制应用位置：相对于其他屏幕尺寸）附加到HTML中使用col-md -3和Panel2是col-md-8。

现在问题是我必须为我的Panel2应用大约25％的左值来按照Panel1对齐，否则它会低于它但是这样做会破坏响应性。该设计打破了所有其他屏幕尺寸，只是违反了使用bootstrap进行响应式设计的目的。 （我必须使用原始设计的页眉和页脚，并根据它创建一个仪表板。）

如果不再手动编写和管理屏幕尺寸，设计的方法是什么，所以我使用的只是bootstrap，设计应该在低rez屏幕上工作。

HTML：
