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

Transition only the property users need to see change.

What to review before production
