Production CSS handoff

Review the CSS you will actually ship

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.

Copy-ready 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.

What this CSS result proves

Backdrop blur only reads as glass when there is real content behind it.

What to review before production

Check contrast over busy backgrounds and keep a readable fallback background for unsupported or reduced-effect contexts.
