Bootstrap 3: adding a new set of columns

twitter-bootstrap twitter-bootstrap-3 less mixins
Facundo Colombier picture Facundo Colombier · Jun 5, 2014 · Viewed 27.2k times · Source

I've been using Bootstrap 3 for a while and now I need to make a new set of extra small columns for horizontal mobiles (e.g. 384px screen width) and after this use it as follows:

col-xxs-1, col-xxs-2, col-xxs-offset-5, hidden-xxs, etc.

Are there some Bootstrap Less mixins for this purpose? I'm not sure how to use them

edit:

There is a Bootstrap mixin called .make-grid(), but I can't make it work.
