Add very short description on product lists (category and homepage)

[paleoglobe]

Hey all,

I work with prestashop 8.1.0.

• I would like to add a very short description on my product lists (category and homepage). How can i do that? I only have very limited experience with coding.
• Ideally I would also like to see 3 products per line on my homepage (instead of 4), so they would show bigger. Can i easily adjust this?

 

Thanks
Christophe
