What this generates
This page generates a CSS multi-column masonry layout. Uses the CSS columns property (widely supported) rather than the newer, Firefox-only grid-template-rows: masonry, so items flow into a Pinterest-style column layout with break-inside: avoid.
Change the fields above and the output updates live -- copy it once you're happy with the result.

Does this send anything to a server?
No. The snippet is built in your browser from the fields you fill in. Nothing is uploaded, logged, or sent anywhere.
Can I use this output directly in production CSS?
Yes -- copy the output into your stylesheet or component. Adjust class names and selectors to match your project's naming, since the generated selectors are generic placeholders.
