removed all borders w/ quick CSS – still want short separator borders to work

Hi there,

Thank you for the great theme and support!
Please can you help me figure this out?
I have used the following CSS that I found on the forum to remove all borders from the nav menu and all containers throughout the entire theme. I still want to use the short separator to create lines under text or headings – how do I exclude the short separator from this CSS override?
