Updated
Formatted CSS will appear here...Quick answer
A CSS formatter reformats compact or messy CSS into readable code: one declaration per line, the opening brace on the selector line, the closing brace on its own line, and a space after each colon. Paste your CSS here and it formats instantly in your browser. Choose 2 space, 4 space or tab indentation, optionally add a blank line between rules and lowercase hex colors, and it safely preserves strings, url() data URIs, calc() spacing and pseudo selectors. Copy or download the .css when done.
CSS Formatter Features
Why Use Free Online CSS Formatter and Beautifier?
Readable in One Click
Paste minified or messy CSS and get one declaration per line, braces placed cleanly and consistent spacing, instantly and in your browser.
Your Indent, Your Style
Choose 2 spaces, 4 spaces or tabs, toggle a blank line between rules, and optionally lowercase hex colors to match your project's code style.
Safe by Design
A tokenizer protects strings, url() data URIs, calc() spacing and attribute selectors, so pseudo selectors like a:hover and :root are never mangled.
Format or Minify
Flip to Minify to collapse the same CSS back into a compact production file, then flip back to Format to expand it again for editing.
100% In Your Browser
Your CSS never leaves the page. All formatting runs client-side in JavaScript, so nothing is uploaded to a server and nothing is stored.
Copy or Download .css
One click to copy the formatted result to your clipboard or download it as a ready-to-use .css file for your project.
What People Use the CSS Formatter For
Inspect Minified CSS
Beautify a compressed vendor stylesheet so you can read it and understand which rules to override.
Cleaner Code Reviews
Format CSS consistently so diffs are small and reviewers see real changes, not whitespace noise.
Learning CSS
Expand compact CSS into readable structure to study how a rule block and its declarations fit together.
Fixing Pasted CSS
Clean up CSS copied from the browser dev tools or a snippet into tidy, consistent indentation.
How It Works
Paste Your CSS
Drop your stylesheet into the input box, or click Load sample to try it. The formatted output appears instantly as you type.
Choose Indent and Options
Pick 2 space, 4 space or tab indentation, decide whether to add a blank line between rules, and turn on lowercase hex colors if you want.
Copy or Download
Copy the clean CSS to your clipboard or download it as a .css file, then paste it straight into your stylesheet or code review.
Tips & Best Practices
Unminify to Read Vendor CSS
Paste a minified stylesheet in Format mode to expand it onto indented lines when you need to understand or override it.
Match Your Team's Indent
Set the indent to 2 spaces, 4 spaces or tabs so the formatted output drops into your codebase without churn in the diff.
Compile Preprocessors First
SCSS, LESS and Stylus are not CSS. Compile them to plain CSS first, then format that output here for the best results.
