      - if you want to hide something for smartphones, but display it elsewhere

      b) d-lg-(flex|block|inline-block...)*
      *meaning that you need to exactly know how to display it in lg, either flex
      or block, etc.

      - say you want to display something in mobiles (tablets and spartphones)
      but not on large devices (desktop) you just need to apply this class to your element
