Developer Scenario: Refactoring a Minified Component Stylesheet

A frontend engineer needs to debug a minified vendor CSS file by expanding compressed single-line rules into readable, indented declaration blocks.

Minified Input	.btn-primary{background-color:#2563eb;color:#fff;padding:.5rem 1rem;border-radius:.375rem;font-weight:600;display:inline-flex;align-items:center;transition:background-color .15s ease-in-out}.btn-primary:hover{background-color:#1d4ed8}
Formatted CSS	.btn-primary { align-items: center; background-color: #2563eb; border-radius: .375rem; color: #fff; display: inline-flex; font-weight: 600; padding: .5rem 1rem; transition: background-color .15s ease-in-out; } .btn-primary:hover { background-color: #1d4ed8; }

💡 The beautified stylesheet makes it easy to inspect overrides, audit CSS specificity, and tweak design tokens.

Frequently asked questions

Does this CSS formatter support modern CSS features like CSS variables and nesting?

Yes. It fully supports custom properties (--css-variables), CSS nesting syntax, @keyframes, @media queries, and modern selector pseudo-classes.

Does my CSS stylesheet get sent to any remote server?

No. All tokenization, formatting, and minification run 100% locally in your web browser. Your private stylesheets and design tokens never leave your computer.

Can I sort properties alphabetically?

Yes. Toggle the "Sort Properties" option to automatically reorder declarations inside every selector alphabetically.
