Docs stylesheet clashes with Clank stylesheet

[Wolfr]

Find elegant solution how to split the two

Ideas

• Namespace everything (too much work, high maintenance)
• Put demos in iframe (will break Angular)
• Use style scoped http://css-tricks.com/saving-the-day-with-scoped-css/ (not enough support right now)
