Where are the CSS files?

Hi, I am just getting started with angular and Webpack. I came across your great example. It does not run as is. After some digging I found it needs an update to zone.js "zone.js": "^0.8.12" I'd create a pull but it seems really simple to fix.

npm start

webpack-dev-server --inline --progress --port 8080
