CSS Formatter

What is a CSS Formatter?

A CSS formatter takes minified or inconsistently styled CSS and reformats it with one declaration per line, consistent spacing around braces and colons, and clear separation between rules. This makes stylesheets far easier to read, edit, and maintain.

Our CSS Formatter uses a robust beautification engine that correctly handles selectors, nested at-rules like @media and @supports, comments, and shorthand properties, producing clean and predictable output every time.

How to Format CSS

• Paste your CSS, or click Sample to load an example stylesheet
• Choose 2 spaces, 4 spaces, or tabs for indentation
• Each rule is expanded with one property per line for readability
• Media queries and nested at-rules are indented to show their structure
• Click Copy to copy the formatted CSS to your clipboard

Why Format Your CSS?

Readable CSS is maintainable CSS. When every declaration sits on its own line with consistent indentation, you can scan a rule at a glance, find the property you need, and make changes confidently. Minified CSS, by contrast, hides structure and invites mistakes.

Developers format CSS when inspecting compiled output from preprocessors like Sass, cleaning up styles copied from other sites, reviewing third-party stylesheets, and standardizing formatting across a team. Consistent formatting also produces cleaner diffs in version control.

Privacy

Formatting runs entirely in your browser — your CSS is never uploaded, so the tool is safe to use with proprietary or unreleased styles.
