Hidden/Visible Responsive Utilities

I just did a new install with the latest Sage 8 release which includes Bootstrap 4 beta. I can’t get any of the new responsive classes to work.

For one example, the new class name: .hidden-xs-down – does not seem to work, neither do any others.

Nothing to do with Sage

My bad but interesting. Looks like Bootstrap made some hefty changes.

Thanks Ben!
