Anyone using Boostrap 4's hidden-*-up or hidden-*-down classes?

They look awesome, but they're not working for me in BS4. In fact, the Webkit inspector tells me that they are missing from my Boostrap.css file. Could this be the case? Can anyone shed some light? Thanks!

Thanks for starting this thread! The hidden-* properties have been removed in the Bootstrap 4 beta. Now there are other responsive visibility properties (you can also see them in the responsive display group when working on a Bootstrap 4 design in the app).

Ah, ok. Looks like my Bootstrap 4 info was not the latest and greatest. I'll check out the new display classes. Thanks, Martin!
