I'm guessing the "bad" css is created by stylus, maybe just an upgrade to stylus will fix it.

(for more information see: postcss/autoprefixer#473)

I will create a PR to fix this if the author tells me it is likely to be accepted. @furqanZafar, please let me know. The presence of these warnings is messing up the build process on my project and I'd like to get this resolved quickly.

[mvolkmann]

Can someone tell me how the file themes/index.css gets generated? I see that it isn't in the GitHub repo.

[elisherer]

Look for
# create dist/index.css
In gulpfile.ls

I didn't see any further action on this so I opened a PR that should fix the issue: #130

@furqanZafar any chance we can get a release for this soon?
