Does it support CSS variables and modern CSS?

Yes. The formatter handles CSS as text with structural rules (braces, colons, semicolons), so it correctly formats CSS variables (--primary-color), calc(), clamp(), custom properties and any modern CSS syntax.

Will it break vendor-prefixed properties?

No. Vendor prefixes (-webkit-, -moz-, -ms-, -o-) are treated like any other property and formatted normally on their own line.

Can I beautify SCSS or Less?

Basic SCSS and Less files without complex mixins, functions or loops will format correctly since they share the same brace-and-property structure as standard CSS.

What is the difference between beautifying and linting CSS?

Beautifying reformats the code structure (spacing, indentation, line breaks) without changing the rules. Linting checks for errors, unused rules or style-guide violations. Use beautify first to make the code readable, then lint for quality issues.

Is my CSS uploaded to a server?

No. All formatting runs locally in your browser using JavaScript. Your CSS never leaves your device — safe for proprietary or client stylesheets.

How do I minify my CSS back after editing?

Use the CSS Minifier tool on this site. Paste your beautified CSS, click Minify, and copy the compressed output for production use.

Why Beautify CSS?

CSS gets minified for production — all whitespace, comments and newlines stripped to reduce file size. That is great for performance, but when you need to read, debug or edit that CSS, minified code is nearly unworkable. The CSS Beautifier reverses the process: it expands compressed CSS back into clean, readable form with consistent indentation, one property per line and proper spacing around braces and colons. Whether you are debugging a third-party stylesheet, reviewing inherited code or editing a downloaded theme, beautified CSS saves significant time.

What Gets Formatted

Element	Formatting applied
Selectors	Each selector on its own line, opening brace on same line
Properties	One property per line, indented 2 spaces
Values	Space after colon, semicolon at end of each declaration
Media queries	Inner rules indented an extra level
Comments	Preserved on their own line

Before and After

.card{background:#fff;border-radius:8px;padding:1rem;box-shadow:0 2px 4px rgba(0,0,0,.1)}.card h2{font-size:1.25rem;margin-bottom:.5rem}

.card {
  background: #fff;
  border-radius: 8px;
  padding: 1rem;
  box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
}
.card h2 {
  font-size: 1.25rem;
  margin-bottom: .5rem;
}

Beautify vs Minify

Use the CSS Beautifier during development for readable, editable code. Before deploying to production, use the CSS Minifier to strip whitespace and reduce file size for faster page loads. The two tools are complementary — beautify for humans, minify for browsers.

When to Beautify CSS

Debugging a live site — copy CSS from browser DevTools (which strips formatting) and beautify it to read it properly.
Editing a downloaded theme — WordPress and other CMS themes often ship with compressed CSS; beautify before making edits.
Code review — minified CSS is unreadable in pull requests; paste it here to produce a readable diff.
Learning from third-party code — expanding compressed stylesheets makes it easier to understand how a design is built.
After build-tool output — CSS preprocessors like Sass sometimes produce tightly compressed output; beautify to review before committing.
