How to code square photos for product block

Site URL: https://www.lilactreemakes.co.uk

Hi all,

I'm looking for a little help with product blocks.  I am trying to put some on my homepage but they are pulling the original photo size - I'd like them all to be 1:1 squares instead.  I can't see how to do this on "Site Styles" so am thinking that CSS would be my only option?  Grateful for any help!

Thanks,

PS My new website isn't live yet!  But if you need further info let me know.

Just answered my own question - I just created 1:1 product thumbnails.... 🤦‍♀️

Thanks anyway everyone!!
