Where can I find suitable content for woocommerce customization for my layout?

Question

WordPress

There is a bootstrap layout, I'm studying how it can be revived using Wordpress. How to pull the topic of information on the Internet is full, I figured it out, with custom fields too. But that's how things got to woocommerce, it became difficult to search for information. The only thing I could find was the output of product cards through snippets. but here's how to change the layout of these snippets, I can not find information.
How the output looks now
as it should, the question is how to display three columns, not four, how to display this thumbnail with a slider, not pictures
