Css Container Queries

What it does

This skill allows AI agents to generate CSS using container queries. Container queries apply styles based on the size of a containing element, rather than just the viewport. This enables responsive designs that adapt to different contexts within a page, such as sidebars or custom containers.

When to use it

• Responsive components: When you need a component to adjust its layout and styling based on the width of its parent container.
• Custom layouts: For creating complex layouts where elements should behave differently depending on their surrounding context.
• Adaptive design systems: To build reusable UI components that automatically adapt to various container sizes within a larger application.
• Dynamic content areas: When designing for pages with variable content widths, ensuring consistent styling across different scenarios.

Key capabilities

• Generates CSS container queries.
• Adapts styles based on parent element size.
• Supports responsive component design.

Example prompts

• "Generate a CSS container query to make this card take up 100% width when its container is less than 600px wide, and 50% otherwise."
• "Create a container query that changes the font size of an element based on the height of its parent div."
• “Write CSS for a sidebar that collapses to a smaller width when viewed inside a narrow container.”

Tips & gotchas

• Ensure your AI agent has a good understanding of CSS syntax and responsive design principles.
• Container queries are relatively new, so browser compatibility might be a consideration for older projects.
