I just created [awesome-guitar](https://github.com/btnwtn/awesome-guitar), for all things guitar related. I would love help pushing resources to the list if anyone has suggestions! @d3viant0ne I would contribute to a skateboarding list.

I would like to propose dropping the `-ns`, `-m`, and `-l` suffixes and introduce using `@` to denote responsive modifiers. I took this idea from [CSS Wizardry's BEMIT](http://csswizardry.com/2015/08/bemit-taking-the-bem-naming-convention-a-step-further/#responsive-suffixes) article, implemented...

@thangngoc89 it should be worth noting that `flex: 1` doesn't produce the same results in IE11 and some older, but still popular, versions of Safari.

If you would like to create an example and add it to the README, I would be more than happy to accept your PR! 👍
