I couldn't really believe that there's really a gap in the media queries for screens larger than 480px and smaller than 768px. This quick (and very short) drop in fixes that.
How to use it: `col-s-1` etc. (whatever amount of columns you set in your variables #LESS
Keep in mind that this will change the behavior of your `col-xs-n` columns as those are then downsized to account only up to 480px screen width.
