showing and hiding of the elements across different devices of different sizes is a real pain in the a**. Here are the bootstrap classes you can use to show hide elements which might come in handy.

Screen Size  Class
Hidden on all .d-none
Hidden only on xs .d-none .d-sm-block
Hidden only on sm .d-sm-none .d-md-block 
Hidden only on md .d-md-none .d-lg-block
Hidden only on lg .d-lg-none .d-xl-block
Hidden only on xl .d-xl-none 
Visible on all .d-block
Visible only on xs .d-block .d-sm-none
Visible only on sm .d-none .d-sm-block .d-md-none
Visible only on md .d-none .d-md-block .d-lg-none
Visible only on lg .d-none .d-lg-block .d-xl-none
Visible only on xl .d-none .d-xl-block
