Bootstrap Classname Mapping

I am a developer responsible for consuming the output of Webflow and turning it into a dynamic react + boostrap application.

I am trying to create a [mental?] map of your w-col classes, and figure out how col-3 maps to the bootstrap 3 grid classes. Is that assumed to be the md breakpoint? Is there a list somewhere of what webflow changes the classes from / where it derives the grid?
