Styled Components

Summary

A CSS-in-JS library that lets you write actual CSS inside JavaScript/TypeScript, scoped automatically to the component that defines it. The approach can improve component-local styling and dynamic theming, but developers should understand rendering costs, server rendering considerations, and alternative styling strategies.

• 1Convert one React component's CSS module into a styled-component. Validate your understanding by applying it in a small practical example.
• 2Practice passing props into a styled-component to change its styles dynamically. Test it with at least one normal case and one edge case so you can explain the behavior confidently.
• 3Learn the runtime cost trade-off vs zero-runtime alternatives like Tailwind.
