Style in React

前端模塊化以後，CSS也能向模塊同樣導入， 以前提倡JS 與CSS分離，如今JS和CSS混合的方式又開始流行了。

CSS與JS分離

CSS Modules

• No more conflicts 沒有名稱衝突
• No global scope
• Composing from other files
• Composing from global class names

CSS in JSS

JSS

• Theming 利用 ThemeProvider 和 theme 封裝組件

1. withTheme

1. ThemeProvider

Benefits

• Theming support out of the box.
• Critical CSS extraction.
• Lazy evaluation - sheet is created only when component will mount.
• Auto attach/detach - sheet will be rendered to the DOM when component is about to mount and will be removed when no element needs it.
• A Style Sheet gets shared between all elements.

Styled-component

• 經過props 修改style

• extend 繼承

• Theming

1. styled-components has full theming support by exporting
2. a <ThemeProvider> wrapper component. 
3. Function themes
4. Getting the theme without styled components
