I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:
```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```
This PR contains the result against the examples folder.
Instead of bundling `postcss-cli` we can now make use of `@zeit/with-css`.
This also means we can get rid of the `<style>` import and concurrent build step for css. 🎉
