[Dev] Modularize CSS

[SBoudrias]

Currently the CSS is not modularized.

We should break up each part of the site in separate modules/files and keep those focuses.

It could be a good place to start using SASS too, but that is not required. Go on as you feel it!

Can we go with PostCSS?

[eddiemonge]

Or use the JS version of sass

[kevva]

👎 for Sass and 👍 for PostCSS (if any).

Personally I'd prefer stylus but i know not every likes that.

[arthurvr]

I prefer PostCSS, personally.

The person who send us a PR get to choose which tool/language we'll use :)

I'll see if I can work on a PR.
