Upgrading from v5? See the migration guide.

Utilizing tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allow you to write actual CSS code to style your components. It also removes the mapping between components and styles – using components as a low-level styling construct could not be easier!

const Button = styled.button`
  color: grey;
`;

Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries.

const Button = styled.button({
  color: 'grey',
});

Equivalent to:

const Button = styled.button`
  color: grey;
`;

styled-components is compatible with both React (for web) and React Native – meaning it's the perfect choice even for truly universal apps! See the documentation about React Native for more information.

Supported by Front End Center. Thank you for making this possible!
