This repo includes an example of the technique for automatic generation of media-query-free stylesheets with desktop styles for IE8 from existing mobile first responsive stylesheets. Requirements are use of Sass (>= 3.2) and mixins for responsive style definitions.
Simply clone the repo, run the following commands and open
sass main.sass main.css sass ie.sass ie.css
Credit for the initial idea goes to my coworker Beni.
