What problem does it solve?

Modern CSS development often struggles to keep layouts responsive and maintainable as design systems evolve. This skill provides a concise approach to applying container queries, advanced selectors, and cascade layers to create scalable, future-proof styles.

Core Features & Use Cases

• Container queries for component-level responsiveness.
• :has() and :is()/ :where() for expressive selectors with controlled specificity.
• Cascade layers via @layer to define explicit cascade order.
• CSS variables for theming and design token management.
• Real-world use case: craft a reusable card component that adapts to container size with minimal CSS changes.
