Container Queries

Container Queries allow CSS to adapt styles based on the parent container's size rather than the viewport, enabling more flexible, component-centric responsive design.

Supported in modern browsers via @container and container-type.

Adopt Container Queries when:

• Building reusable components for varied layouts.
• Designing for complex grids or multi-column pages.
• Moving beyond media queries for nested responsiveness.
• Enhancing design systems with self-contained styles.

Note: Use container-type: inline-size for most cases.

Combine with CSS Grid for powerful layouts.

Test with ResizeObserver for dynamic sizing.
