I was using Lay Theme to create a portfolio and using a thumbnail grid I found an unexpected border-right of 1 or 2 pixels that can't be detected with the inspector or hidden with custom CSS.
Here are two examples of it:
The website is for a design studio and they need it to be very clean so for sure they won't accept this result. I'm so worried about it because it's kind of urgent.
Any ideas? Why is this happening and what can I do to fix it?
Thanks a lot!
