I think, we just need to add the html and css folders to the webpack config here under extraWatchDirs (https://github.com/fun-stack/example/blob/master/webapp/webpack.config.dev.js#L7). Though, it needs to run webpack again. So that means you need to run webpack on watch, which we currently not do.

I think the webpack devserver already takes care of the html bundling when it changes. So it might be simple.
