Are you tired to write in your templates always the same classes 'column', 'row', 'span' and so on?
Use your semantic class names and give them a structure directly in your css using GiGi, the Grid Generator system for devs
$ npm install --save-dev gigi
Import gigi.scss in your file.s[ca]ss
@import "gigi/gigi"
if you are using node-sass you can set the include path to use the file installed by npm, also if you are using gulp-sass or grunt-sass.
includePaths: ['./node_modules/']
