Choose axis, strictness, alignment, padding, and snap-stop behavior with a live preview.
Runs locally in your browser. Generated CSS is not deployed or tested against your site automatically.
This panel stays locked until you review the generated output above. It checks output shape, feature dependencies, motion/fallback concerns and creates a copy-ready component handoff.
Generated component handoff will appear here.
Browser support is checked against the browser running this page, not every browser you support. Treat this as a production preflight, then test the copied CSS in your real component, content, cascade and target browser matrix.
Author per-side scroll-padding and child scroll-margin, then test the exact snap behavior in a real overflow container before copying the container and child CSS.
Drag or wheel inside the preview to test snap behavior. Browser input devices and reduced-motion settings can change how the scrolling feels, but the CSS rule itself is shown exactly below.
Generated CSS should be judged by the real output, not just the controls.
Copy the output into the actual component, test its layout/content extremes, and review browser support, fallbacks and accessibility before production use.
