<div class="col-sm-8"><h2>Large, Small or Tiny</h2><p>
The new fluid grid comes in 3 flavors, or actually sizes. The large grid <code>col-lg-*</code> works exactly like the Bootstrap 2.x <code>span*</code> did.
There is also a small grid that is realized using the <code>col-sm-*</code> classes. This smaller grid is ideal for smartphones and tablets.
Finally, there is the non-stacking tiny grid <code>col-*</code> that is intended for very small screens less that 480px.

Bootply is a playground for Bootstrap. Designers and developers use Bootply to edit, design, prototype, test and find examples that use Bootstrap 3.
Use Bootply to hand-code HTML, Javascript, CSS and drop in the Bootstrap classes. There is a also a visual drag-and-drop builder that is perfect for wire-framing and mockups.

首先将其添加到您的体型：
overflow-y: scroll;
然后将其添加到样式文件中的col-sm-2类：
overflow-y: scroll;
height: 100vh;
您也可以在jsfiddle！
