About CSS container queries
CSS container queries let components respond to the size of their parent container instead of the viewport. They are useful for cards, panels, widgets, sidebars, and reusable layout components.
This generator creates the container setup and the @container rule together, so you can quickly copy a complete responsive component pattern.
How to use this generator
- Choose a container type, usually inline-size for width-based component layouts.
- Set an optional container name if you want named container queries.
- Choose a min-width, max-width, min-height, or max-height condition.
- Enter the selector and CSS declaration that should apply inside the container query.
- Copy the generated CSS into your stylesheet.
Tips
- Use container queries when a component should adapt to its own available space.
- Use media queries when the layout depends on the whole viewport.
- Named containers are helpful when nested components have multiple possible query containers.
- Keep component selectors local and predictable, such as .card, .panel, or .product-card.

CSS Container Query Generator FAQ
What is a CSS container query?
A container query applies CSS based on the size of a container element, not the browser viewport.
When should I use container queries instead of media queries?
Use container queries for reusable components that need to adapt inside different layouts. Use media queries for page-level viewport changes.
What does container-type: inline-size mean?
It enables querying the inline axis, usually the width of the container in horizontal writing modes.
Do I need container-name?
No. Container names are optional, but they are useful when you want to target a specific named container.
