What is CSS Container Query Generator?
CSS Container Query Generator is a visual tool for building @container rules and container-type declarations. Container queries let components respond to their parent container size rather than the viewport, enabling truly modular, reusable responsive design. Set container types (inline-size, size, normal), name containers, define min/max width query conditions, preview behavior live, and copy production-ready CSS.
Key Benefits
- Component-driven responsive design
- No viewport-dependent media queries
- Named containers for targeted styling
- Live preview of query activation
- Copy-ready CSS output
Common Use Cases
- •Card components in flexible layouts
- •Sidebar and main content areas
- •Reusable design system components
- •Modals and nested panels
How to Use the CSS Container Query Generator
- Choose container type: Pick inline-size (width queries), size (both axes), or normal (no containment).
- Name the container: Optionally set a container-name like "card" so nested elements can target it specifically.
- Set @container conditions: Enter min-width and max-width values for the query (e.g. min-width: 400px).
- Preview and copy: Drag the preview slider to see the query activate, then copy the generated CSS.
