CSS beautifier

What is a Css Beautifier?

Minified CSS from a production build or a third-party library is hard to read, and hand-written stylesheets drift into inconsistent formatting over time. The CSS beautifier reformats your code with consistent indentation, line breaks and spacing, without changing what it does.

How to use it

  1. Paste CSS, minified or messy.
  2. Choose the indentation if options are available.
  3. Copy the formatted result.

Example

Input:

.btn{padding:8px 16px;border-radius:4px}.btn:hover{background:#2563eb;color:#fff}@media(max-width:600px){.btn{width:100%}}

Output:

.btn {
  padding: 8px 16px;
  border-radius: 4px;
}

.btn:hover {
  background: #2563eb;
  color: #fff;
}

@media (max-width: 600px) {
  .btn {
    width: 100%;
  }
}

When to use it

  • Reading or debugging minified CSS from a website or package.
  • Cleaning up copied snippets before adding them to a project.
  • Making a diff readable before a code review.

Beautify vs. lint

A beautifier only changes whitespace and layout. It will not detect invalid properties, duplicate selectors or specificity problems; use a linter such as Stylelint for that. For ongoing projects, configure Prettier in your editor so every file is formatted the same way automatically, and use this tool for one-off cleanups.

Formatting runs entirely in your browser.

Frequently Asked Questions

Does beautifying CSS change how it works?

No. Only whitespace and line breaks change. Selectors, properties and values stay the same.

Can I beautify SCSS or Less?

Plain CSS formats best. Simple SCSS often works, but nesting and mixins may not be formatted perfectly.

What is the difference between a beautifier and a minifier?

A beautifier adds whitespace for readability, while a minifier removes it to reduce file size.

Should I commit beautified CSS?

Commit readable source CSS and let your build tool minify it for production.

Is my CSS sent to a server?

No. The formatting runs entirely in your browser, so private or unreleased stylesheets never leave your device.

Can it fix broken CSS?

It formats valid CSS. Missing braces or semicolons can produce odd output, so fix syntax errors first or run the code through a linter such as Stylelint to locate them.
