Serif lite theme problem

I am new to using wordpress and websites in general. Im using the Zerif Lite theme. I have figured out the simple things about the theme. My question is dealing with the big title section. I was wondering if there is a way to reposition the Big Title text and buttons. Is there a way to move the Title and buttons to be positioned more at the bottom of the background image instead of being centered? I have looked through the style.css, but have not found anything. Can anyone help with this simple problem im having?
