}Container Queries
Container queries (now a stable baseline in 2026) allow elements to style themselves based on the size of their parent container rather than the viewport. This unlocks true component-driven design.
CSS Subgrid
Subgrid allows nested grids to participate in the sizing of their parent grid. Perfect for aligning headers, bodies, and footers across multiple card components in a grid layout.
