how to make this page as mobile responsive :
Hello i am still new here
But i would recommend commenting out all your elements except for the first one and check it for responsiveness, once your happy then uncomment the next element.
With the tables using boot strap
i would check out https://hackerthemes.com/bootstrap-cheatsheet/#col-sm-1
if you click on the class it will show you a sample and you can resize your browser to check out the responsiveness
Seems like there is many way to do it, i am interested in best practice to do it.
