Hi @ninadovetail,
Welcome to Storefront. 🙂
I assume you are wanting horizontal lines that look something like these obnoxious purple ones I drew up in my example below?

If so, there are ways to do this potentially with the new block editor or using the Additional CSS section. How have you built this page so far, out of curiosity?
I recently inherited this site from someone who built it years ago, and have had to pretty much figure it out on my own how to make changes, etc.
I’d love to just add into the additional css section, if possible. I’m hesitant to upgrade to the version with the block editor but if that’s what it’s going to take, I will try it as a last resort.
I’m still unclear how the products are coming up on the landing page — I feel like if I learned how that works I could figure out how to customize the product section eventually.
Thanks again.
Scratch the horizontal line question — figured it out. Just how to remove the copyright footer. Thanks!
