[Documentation]Animation

I often have been asked that how to deal with animation with React.
I can find the sentence in reactjs.org.

React can be used to power animations. See React Transition Group and React Motion, for example.

• https://reactjs.org/docs/faq-styling.html#can-i-do-animations-in-react

I think it would be nice if there is an Animation page in the Advanced Guides section.
What do you think?

The page would cover the following topics

• Animation using style prop
• Animation using className prop
• Animation using community libraries
  • react-transition-group
  • react-motion
• ... and more?

Thanks!

從現有的 React styling FAQ（位於 reactjs.org/docs/faq-styling.html#can-i-do-animations-in-react）開始，並檢視文件網站中的 Advanced Guides 結構。定義一個 Animation 頁面，涵蓋使用 style 和 className 的方法，以及 react-transition-group 和 react-motion，並在撰寫之前決定範圍和任何其他主題。
