Make your website work across screen sizes.
Improves website layouts across screen sizes, builds responsive layouts, and provides live previews at multiple widths.
When to use it
Use when building responsive layouts, fixing mobile layout issues, adding breakpoints, handling sticky or scrolling layouts, or previewing screen widths.
Give it a responsive design task; it asks discovery questions and works with you on design decisions, with optional behavior specs and approval before coding.
What you provide
Node.js is required for the bundled live-preview and snapshot tools, rather than for the responsive coding guidance itself.
The optional snapshot feature requires dev-browser for headless screenshots.
