What this tool does
CSS Formatter formats and cleans CSS so selectors, declarations, and blocks are easier to read.
← All Tools
🎛️ CSS Formatter
Format CSS rules, declarations, media queries, and nested blocks.
Why it is useful
It helps debug copied styles, minified snippets, generated CSS, and stylesheet fragments before editing.
How it works
The browser parses or normalizes CSS text into a more readable indentation and spacing pattern.
Best input
Paste valid CSS or a stylesheet fragment that needs formatting.
Debugging tip
Format first, then look for missing braces, duplicated declarations, or overly broad selectors.
Privacy note
CSS formatting happens locally in your browser.
Important limitation
Formatters improve readability but do not prove CSS is correct, optimized, accessible, or cross-browser safe.
Quick answers
Can it minify CSS?
Use minify controls if available; otherwise it focuses on readability.
Will it fix invalid CSS?
It may expose issues, but it is not a full CSS validator.
Common Use Cases
Clean up minified CSS snippets
Paste compressed rules from a bundle, CMS, or browser inspector and turn them into readable blocks before editing.
Review generated styles
Format output from design tools or AI code suggestions so missing braces and duplicated declarations are easier to spot.
Prepare stylesheet fragments for docs
Make a copied CSS example readable before adding it to documentation, tickets, or code review comments.
