Three Column on each row in avada theme

I am using Avada Theme for my site. Here is the link

I want to show three products in each row. There are four rows on each columns. I have checked the avada theme settings/options to show post/products, they are currently three columns. I am using post-in-page plugin to show products on home page. Could you please guide me where i should change columns per row in avada theme?
