Bootstrap within shortcode

I would like to implement a shortcode (indeed a Divi extension but it’s almost the same I guess) using Bootstrap.

How would I do it without causing conflicts with the theme?

I think I should prefix all the classes but how would I do it?
I have read that I could use LESS but I don’t get how to do it in Bootstrap:

Thanks in advance, Alessio
