Can't get sidebar down the entire page

Hi there,
I am have been trying to get the sidebar to go all the way down the webpage, but cannot seem to do it. Any advice?


You can try use height in vh(viewport height) units. It should work.
height: 100vh , it will take full height of viewport. You can customize according to your use.
There might be scrollbar issue after that. You can use overflow:hidden property in body tag.

Hope it helps.
