Does this remove my comments?

Comments are removed during formatting to keep the reformatting logic simple and reliable — use the original file if you need to preserve comments.

Is my CSS uploaded anywhere?

No — formatting happens entirely in your browser.

Does this validate my CSS syntax?

No — it reformats structure but does not check for invalid property names or values.

Does this support CSS custom properties (variables)?

Yes — custom properties like --main-color are treated like any other declaration.

Does it handle nested @media queries?

Yes — brace-based nesting, including @media blocks, is indented according to its nesting depth.

Does this work on very large stylesheets?

Yes, limited only by your browser's available memory.

What Is a CSS Formatter?

A CSS formatter takes minified or messily-written CSS and rewrites it with each selector, property and closing brace on its own properly indented line, making a stylesheet's rules easy to scan and edit.

It's especially useful when working with third-party or minified CSS that needs to be read, debugged, or partially copied into a project in a readable form.
