CSS Formatter
Reindent and tidy minified or messy CSS stylesheets for readability. Paste any CSS, choose 2 or 4-space indentation, and get clean, properly formatted rules back instantly — all processed locally in your browser.
Why We Built This Tool
A minified stylesheet crushes every rule onto one line, making it hard to scan for a specific selector in dev tools. This formatter reconstructs the visual structure of your CSS — one rule, one declaration per line — without changing a single value.
How to Use It
Paste your CSS, choose 2 or 4-space indentation, and select "Format CSS". The tool rebuilds each selector block and its declarations onto properly indented lines, giving you a readable stylesheet back instantly, entirely in your browser.
Common Mistakes to Avoid
Formatting a live production stylesheet directly
Solution:
This tool is for reading and understanding CSS, not for safely editing a live deployed stylesheet. Edit your actual source files, then minify as part of your normal build process.
Assuming formatting validates your CSS
Solution:
This tool reindents based on braces and semicolons — it does not check for invalid properties, typos, or browser support.
Expecting comments to be preserved with exact formatting
Solution:
Comments are stripped before reformatting to keep the indentation logic simple. If you rely on structural comments, keep a separate annotated copy of your source.
Frequently Asked Questions
No — it reindents based on structure (braces, colons, semicolons). It does not check property names or values for correctness.
No. Formatting only changes whitespace — no selector, property, or value is altered, so rendering is unaffected.
Yes — toggle between 2-space and 4-space indentation before formatting.
No. Formatting happens entirely in your browser — nothing is sent to a server.
Why formatted CSS matters
A minified stylesheet crushes every rule onto one line, making it difficult to scan for a specific selector or property using browser dev tools. Formatting restores the visual structure of the cascade.
How the formatter works
The tool tracks braces, colons, and semicolons to rebuild each selector block and its declarations on separate, properly indented lines — without changing any selector, property, or value.
Safe and non-destructive
Reformatting only changes whitespace. The resulting CSS behaves identically to the original — nothing about how it renders your page changes.
