Beautify or minify CSS for components, email templates, and quick style debugging—entirely in your browser.

When to format CSS online

Copied styles from devtools or legacy pages often arrive as one line. A css formatter online restores readable blocks for review, while minify mode compacts rules for embeds.

Limitations of browser-based CSS formatting

This tool focuses on common rule blocks and declarations. Complex preprocessors (Sass, Less) should be expanded before formatting here.

How it works

  1. 1Paste CSS and pick format or minify to transform output instantly.
  2. 2Formatting splits selectors and declarations onto readable lines.
  3. 3Processing is local—styles never upload to a server.

Examples

Format a card component rule

.card{display:flex;gap:1rem;padding:1.5rem;border-radius:1rem;}

Minify hero section CSS

.hero { padding: 4rem 2rem; background: #111; color: #fff; }

Format media query block

@media (min-width:768px){.grid{grid-template-columns:repeat(2,1fr);}}

Clean utility classes

.btn-primary{background:#4f46e5;color:#fff;border-radius:999px;}

When to use this tool

  • Indent CSS copied from browser inspector.
  • Minify widget styles before embedding.
  • Clean up email template styles.
  • Prepare readable snippets for design reviews.
  • Compact utility CSS for documentation.
  • Pair with HTML formatter for markup plus styles.
