Ways to go about simple formatting issues like this? My site does everything I need it to do as a retail store, what I struggle with is the beautification of it. I want the product gallery to go down exactly as far as the list of products goes, how would I go about that? Any tutorials?

To add since i can’t type as much as I would like in the actual post, how can I get the gallery to look more clean and not have random rows that aren’t filled? I would also like to get rid of the option “No thanks, I don’t need this” I think it may be a woocommerce function but I haven’t found it yet. Any help is greatly appreciated, thank you.
