The system completely changed. I also had to adapt classes to new
screen breakpoints.
hidden/hide -> d-none
show -> d-block
hidden-xs -> d-none d-md-(block/inline/...)
hidden-sm -> d-md-none d-lg-(block/inline/...)
hidden-md -> d-lg-none d-xl-(block/inline/...)
hidden-lg -> d-xl-none
visible-xs-* -> d-* d-md-none
visible-sm-* -> d-none d-md-* d-lg-none
visible-md-* -> d-none d-lg-* d-xl-none
visible-lg-* -> d-none d-xl-*
hidden-print -> d-print-none
visible-print-* -> d-none d-print-*
...
and all possible combination of those had to be handled too.
