Virtue theme Confused about making child theme based on style.css?

Hi, i’m new to wordpress, so excuse me if i’m wrong about this. I’m trying to make a child theme of virtue right now, but when I looked at the theme’s style.css it seemed very small in comparison to my other pre-installed themes on my wordpress, such as 2012 and 2013.

Below is what I’m getting when I click on the theme’s style.css. Is this what I need to paste into my notepad++ in order to create my child theme? It’s just that the style.css files of my 2012 and 2013 themes are tremendous (like 3000 lines of code), but the style.css for virtue is only like 12 lines.
