[Theme: Klasik] Removing Comment Space

I have removed all ability to comment via the dashboard but there’s a problem. There’s a white space in between widgets.

I am seeking to remove the space between the bottom of the content and the top of the footer. Therefore, I have no need to retain the space between the content and the top of the footer. Currently, there is a line at the bottom of the content and another line at the top of the footer. I would really like to also remove the line below the content as well as the commenting space. I am sure this is a simple CSS fix, but it’s stumped me all afternoon.

Here is link of what i want to remove.
