Shop page align add to cart and details

I am using Avada theme to begin. I am trying to align the add to cart and details to the bottom of each product on the main shop page. There are many codes out there and have tried many of them. However they all crash my site. Does anyone know if there is a code for Avada theme (i’m assuming it is a theme issue) and if so, where to put it?

Thank you, Jillian
