使用样式参数的样式组件与功能组件

Question

I just asked myself what the reason would be to use styled-components over a custom functional component in react other than saving a few LOC. Example code:

const StyledButton = (props) => (
  <button
    style={{
      color: '#E8E8E8',
      padding: '8px 16px',
    }}
    {...props}
  />
);

const jsx = () => <div><StyledButton>Click Me!</StyledButton></div>;

const StyledButton = styled.button`
  color: '#E8E8E8';
  padding: '8px 16px';
`;

const jsx = () => <div><StyledButton>Click Me!</StyledButton></div>;

Kind regards, Thomas

With styled-components you can leverage the full power of css, which means you can:

• Overwrite the css of child tags and classes
• Use pseudo classes such as :visited , :first etc.
• Use hover and other ui states
• Use css variables easily

Just as a few examples, but obviously anything else that css can do by default that would require extra javascript to do with just plain styles.
