Modern component-driven web design requires components that adapt intelligently wherever they are placed inside a dashboard or sidebar.
1. Why Viewport Media Queries Fall Short
A card placed in a 300px sidebar needs a compact layout even on a 4K desktop monitor. Container queries make components truly modular.
2. Container Queries in Action
Declare container-type: inline-size on parent wrappers and query component widths with @container (min-width: 400px).
3. Perfect Card Alignment with Subgrid
Applying grid-template-rows: subgrid aligns headers, images, and CTA buttons across sibling cards regardless of varying text lengths.
