Make a Child theme with the Sensitive Responsive Theme

When I make a child theme, it shows up weird. How do I get the child theme to display like the parent website? In my child theme, all i have now is my style.css which is importing the parent themes css. Nothing else is showing up though.

So what else do I need to include? I tried including all the php files but then that made the theme not show.

It’s showing up like this: https://mountziondev.3guerrillas.com/

Thanks in advance!
