The inuitcss widths-responsive module is an extension of the default widths
module.
Install using Bower:
$ bower install --save inuit-widths-responsive
widths-responsive will inherit the same settings used for widths (i.e.
namespaces and fraction vs. spoken-word format).
widths-responsive loops through the breakpoints defined in
settings.responsive to generate prefixed breakpoint-based classes. If you are
using inuitcss’ default breakpoints, you will be given classes like
lap-and-up-1/4, or desk-one-half, etc.
