Looking to make site identical to preview

I chose this theme because the screenshot of the preview was appealing and I thought that it would look great with what I am trying to do. However, when I installed I noticed that you get the bare bones of the template. I was wondering if you could help me to get it setup like the preview?

I’ve already created the child.

Is there anyway that I could have the code to make my site look like the preview?

I am not very familiar with css. I know enough to install the theme, create the child and manipulate the code, but not enough to write the code myself.

ANY hints would be WONDERFUL!

Thank you.
