Take out unnecessary styling

[markgeraty]

There's a lot of styling included that was probably just meant for demo purposes

Hi!
Agree with markgeraty. All styles are injected internally into index.html for prod build and it is very hard to overwrite them with external bundle styles. Could you pls remove them or make them externally injected to bundle css?
Thanx

Hi! Could you pls remove built-in styling for .flipper-container span? It is very destructive for my layout! Thanx.
