I am developing a website using bootstrap. The requirement was that the menu should be fix on the top even if we scroll down the page. I fullfilled it using bootstrap's navbar class. But now the requirement is a fixed sidebar as well. Even if we scroll down the page, sidebar must retain its possition irrespective of the center content page.
The website should be like w3schools It has a fixed navigation bar at top and a sidebar in left which is not dependent on center content.
