How can I create a simple page vertical scroll bar without using jQuery

Question

I have looked at I think all the scrollbars code but have not yet been able to find a simple one that does not use jQuery or a somewhat complex library.

Has anyone created there own simple scrollbar using just Javascript? What I am looking for is an example of how this can be done.

Surprisingly, there is not a great, simple solution out there using vanilla JavaScript. I made a pure JS lightweight, minimal cross browser solution. Adjust to your own needs and aesthetics

*Update 2019
The W3C has a working document that is on standards track to improve this out of the box through the css specification. Although limiting, if you want to use cutting edge css you can now style your scroll bars through the scrollbar-color and scrollbar-width. For more information please check https://drafts.csswg.org/css-scrollbars/

Here is the fiddle and CodePen
