Create a vertical divider between Features

Hello!

I was able to use the information from this thread to answer my question about how to get a divider line between Features using Custom CSS.

Create Some Border On Page Builder

However, I would now also like to add a few more Feature areas to the homepage but do not want/need the divider lines to show on them. Is there a way to name the Features in CSS and only attribute the dividers to a certain one?
