8 CSS Container Queries
Dive into the new paradigm of component-driven styling using native CSS Container Queries. This collection demonstrates how elements can finally respond to the size of their parent container, not just the viewport, solving the core challenge of responsive component design. This technique achieves true component independence by allowing a single component block to adapt its layout regardless of where it’s placed in the page structure.
