I have a main container div layer that houses all of my page content. Now, I have a vertical border line on either side of the container, but the problem is that I have to set a static height from the css page.

For example, the container height is 600px, but if my page content goes further down to like, 800px, I end up having a 200px gap (a gap, where there is no vertical lines).

Is there any way to make these lines dynamic from just using basic html and css?
