#81

This looks perfect (except the broken build, but it's related to Nyalab/caniuse-api#27).
I just would like one more thing: disable this when IE 8 in not in the browser scope.
Caniuse have some data on this http://caniuse.com/#search=before

Maybe we can add this in the caniuseFeaturesMap in order to do that? Not sure how caniuse-api handle partial support (poke @Nyalab)

Or maybe we should detect if ie8 is passed in option.browser, if no, we pass option to false ?

@magsout yeah. Maybe we should enhance this map in order to accept callback for specific features.

[magsout]

caniuse.isSupported('css-content', 'ie 8') => false

[MoOx]

So, you know what to do then ?

[magsout]

[MoOx]

Can you do 2 things:

• add this to the example (ref https://github.com/cssnext/cssnext#add-a-feature)
• add the plugin link to feature list

And also update the date to tomorrow. I don't want people think it's a joke :D

[magsout]

Done.

[MoOx]

Last thing, if you can change the version in CHANGELOG to 1.2.0 (it's a feature not a patch) + bump in package.json, I will be perfect so I can just do

$ git pull
$ npmpublish

Ref: https://github.com/MoOx/setup/blob/master/functions/npmpublish ;)

[MoOx]

And add "Close #81" in commit description ;)

[magsout]

Done ;)

[MoOx]

Build is broken for example expected output not being updated and some sourcemap fix. I will handle that.

[magsout]

after that I added?

[MoOx]

No before :)
Well for the example.css you didn't update the expected output :p

[MoOx]

I will fix the build and publish. Thanks @magsout
