@gucong3000 I need a little help understanding this PR.

Has postcss-styled been deprecated?

At the moment "styled" is one of the documented options for the syntax option of the Node API. As such, some users might be relying on it and I believe that we'll break their build if we remove it.

(Incidentally, the error message in that last link needs to be updated...)

I updated the code. styled exists as an alias of postcss-jsx

I think it would make sense to add deprecation notice for styled option. Could be done in another PR.

Also, I think we should rename jsx to css-in-js. "jsx" a little bit confusing, because it's not for JSX only, but for many CSS-in-JS syntaxes. This is also something for another PR. If we agree, then we can deprecate both styled and jsx names, and add css-in-js all in one PR.

Should I make any changes to this PR?

SGTM.

Should I make any changes to this PR?

I'd be happy to see the suggestion above rolled into this PR. It'd be great if there was just a css-in-js option, and styled and jsx were aliased to it and deprecated. It'd also be good if we doubled checked all mentions of the syntax options in the code and documentations to make sure they are consistently listed as:

"css-in-js"|"html"|"less"|"markdown"|"sass"|"scss"|"sugarss"

Great job, @gucong3000!

I think deprecation notice better to do in another PR to have things more clear.

@gucong3000 Excellent.

SGTM.
