Use of postcss instead of glamor

[bpetetot]

postcss can inject css into <style> (if you put the extract: false) like glamor
postcss could also bring css-modules, autoprefixer, nano, variables, imports, if we want...

Moreover with postcss we could add sass as preprocessor and consequently we could use (and improve) Kriya as main UI library.

@fabienjuif what do you think about that ?

[fabienjuif]

why we didn't use CSS at first ?

• we wanted a prepbuilt version, with a single JS file to inject into the target webpack
• we didn't want that CSS override the tested component

with css-in-js we could avoid both concerns.
with postcss, I have the feeling that only the first one is resolved.

[bpetetot]

with css-modules, the second one is also resolve. no ?

[fabienjuif]

we still could use :global or use a lib that use :global
