V5 bootstrap hide module

Question

version 5 with a start from scratch template on Joomla! 3.3.6 Stable

it fails me to hide a module through the bootstrap command
module class suffix
.visible-xs on devices other than phones

is the hide of an entire module possible with template toaster bootstrap?

Answer 1

Please try to use the module class suffix as visible-xs (without dot).
Joomla admin -> Extensions -> Module Manager -> Click over the module on which you want to use class suffix -> Advanced -> Module class suffix -> visible-xs

Answer 2
