Elements not showing on different breakpoints

I’m sure this is just a “Duh!” kind of situation. But I can’t figure out why the grid with the white rectangles isn’t showing in any breakpoints smaller than desktop.

Any help is greatly appreciated! :pray:

Not sure why but “overflow” was set to hidden and changing it to visible made everything appear. :man_shrugging:
