I am really interested in software architecture, even in CSS and HTML I found something interesting SMACSS and BEM methodologies.
I am still discovering them, I need advice from more experienced web developers.
I have a lot of places in code like this col-md-4 ....
Specifying like this makes it coupled with Bootstrap in this case.
Maybe in the future I want to use another grid technology, than I need to replace all occurences everywhere in my code.
So SMACSS methodology has separate layer called Layout
Maybe it makes sense to wrap existing bootstrap classes like that
