Styled Components

Pros of

  • styles are part of JavaScript (CSS-in-JS) in this case and allow you to build components from CSS snippets
  • with styled components you can build CSS dynamically based on props and state of the component
  • you don’t have to create tons of class names with related CSS declarations written somewhere else. Class names are generated automatically and you don’t have to care about them anymore.
