Does this indent nested @media rules by depth?
It line-breaks their contents, but doesn't add extra indentation reflecting the nesting depth like a fully CSS-aware formatter would.

How this formatter actually works
This formatter adds a line break after each opening brace, semicolon, and closing brace, and after commas in selector lists, turning a minified stylesheet into a spread-out, readable version. It's a flat, regex-based text transformation rather than a real CSS parser — nested rules like `@media` queries get their inner declarations broken onto lines the same way as top-level rules, but without extra indentation reflecting that nesting depth.
For typical, flat CSS rules, this produces a clean, readable result. For heavily nested `@media` or `@supports` blocks, the output is still line-broken but reads more flatly than a fully depth-aware formatter would produce.
Workflow at a glance
Use this quick flow to understand where the tool fits in your work and what to review before relying on the output.
Review checklist
Before
Know that nested rules like @media won't get extra indentation reflecting their depth in this formatter.
After
Check any nested blocks in the output closely, and compare against the original for anything complex.
When a quick reformat is enough
Use it to quickly turn minified CSS — copied from a browser's dev tools or a build output — into something readable enough to scan property by property.

What the formatter does
Line breaks at key characters
Adds a new line after {, ;, }, and commas in selector lists.
Fast for flat CSS rules
Works cleanly on typical, non-nested selector and declaration blocks.
No parser dependency
A lightweight text transformation, not a build tool or CSS parser.
Instant formatting
Output updates as you paste or edit the input.
Formatting CSS step by step
- 1Paste the CSS snippet you want to format.
- 2Review the output as it updates automatically with line breaks.
- 3Check nested @media or @supports blocks especially closely, since depth isn't reflected in indentation.
- 4Copy the formatted CSS into your editor, ticket, or documentation.

Where your stylesheet goes
Formatting happens entirely in your browser using pattern-based text processing — nothing you paste is sent to a server.
Getting a reliable result
- Use this for typical, flat CSS rules rather than deeply nested @media or @supports blocks if depth-aware indentation matters to you.
- Compare the formatted result against the original for anything with unusual nesting before relying on it.
- Run production-bound stylesheets through your project's own formatter (like Prettier) for depth-aware indentation.
- Check comments in the original CSS carried over correctly, since they aren't given special handling.
CSS formatting mistakes to avoid
Expecting depth-aware indentation for nested rules
Nested @media or @supports blocks get line breaks but not extra indentation reflecting their nesting depth.
Assuming this validates your CSS
It reformats text based on patterns — it doesn't check that your CSS is syntactically correct.
Not checking comments after formatting
Comments aren't given special handling in the formatting pass.
Using it as your project's formatter
For production stylesheets, use a proper tool like Prettier that understands CSS's actual structure.
When to double-check the output
CSS Beautifier makes typical, flat CSS rules easy to scan quickly. For deeply nested @media blocks or a fully depth-aware result, a real CSS-aware formatter like Prettier will do a more thorough job.
