Sorry it didn’t do anything 
Topic summary
A user seeks help adding borders and shadow effects to product tiles on their Enterprise theme store.
Initial Solution:
- Another user provides CSS code to add borders and shadows to product cards
- After initial failure, the solution successfully works
Follow-up Requests:
- The original poster asks about increasing card size and spacing (resolved independently)
- New request: Add a bottom border divider on mobile layout only, constrained to box item width rather than full edge-to-edge
Current Status:
- CSS code provided for mobile border using media queries and
:afterpseudo-element - Implementation unsuccessful - border not appearing
- Helper requests clarification on which file the CSS was added to, noting it’s not visible in the storefront source
- Discussion remains open with troubleshooting in progress
