Almost there!

@adao99 this is ready to be merged.

However, I have a few concerns about eslint-plugin-css-modules as it has a lot of bugs and is not functioning correctly when using postcss, e.g.: with nesting, see: atfzl/eslint-plugin-css-modules#25. Moreover, the README says it's not maintained anymore.

We do have https://github.com/bmatcuk/eslint-plugin-postcss-modules which seems better in the sense that uses postcss, and has the exact same rules! I think you briefly mentioned this when we met at OPO.js, correct? Anyway, for the OSS challenge, there's no need for you to change the plugin to the postcss one, unless you want to.

@satazor should this be merged or closed? 🤔

This can indeed be closed!
