About the CSS Formatter

Paste compact or messy CSS to beautify selectors and declarations, check for common structural mistakes, or generate minified output for production snippets. It is built for quick stylesheet cleanup without uploading code.

How the result is produced

The formatter scans braces, declarations, comments, and whitespace to produce readable CSS or compact output. It operates in the browser and does not need a build pipeline or network request.

Example: A compressed rule such as `.card{color:red;padding:1rem}` can be expanded for review, then minified again when a compact snippet is needed.

Limitations and review notes

The tool does not check browser compatibility, cascade behavior, accessibility, or whether a property is supported in a target engine. Review generated CSS in the actual application and build pipeline.

How to use it

  1. 1. Paste a stylesheet or CSS snippet into the input pane.
  2. 2. Choose two-space or four-space indentation.
  3. 3. Use Beautify for readable CSS or Minify for compact output.
  4. 4. Copy the result or download it as a CSS file.

FAQ

Can the CSS formatter minify stylesheets?

Yes. Use Minify to remove comments and formatting whitespace, then copy or download the compact CSS.

Does CSS formatting run locally?

Yes. Beautifying, minifying, and validation checks run in your browser after the page loads.

What validation does it perform?

The formatter checks for mismatched braces, unclosed comments, and unclosed strings before producing output.
