How to use CSS Formatter
Beautify and indent your CSS code.
- Paste the minified or messy CSS into the Your text field.
- Press Run to re-indent every rule with consistent spacing.
- Copy the readable stylesheet back into your editor.
Practical note. Paste in any minified stylesheet and the formatter rebuilds the indentation and line breaks. Very long rules stay on one line, matching the conventions of most CSS style guides.
When you actually reach for this
- You received a minified stylesheet and need to read or edit it, so you want readable indentation and line breaks.
- You want to normalize formatting across a team so diffs stop showing pure whitespace noise.
Where this tool stops being accurate
- Pretty-printing cannot fix invalid CSS — it only reformats what parses, and a broken rule may be silently dropped by the parser.
- It does not reorder properties or merge duplicates; two declarations of the same property both remain.
Frequently asked questions
What does CSS Formatter do?
Beautify and indent your CSS code.
Will formatting my CSS change how it renders?
No, whitespace between tokens is insignificant in CSS, so reformatting only changes readability, not the computed styles.
Why did a rule disappear after I formatted it?
The formatter parsed the file first; a syntactically invalid block that the browser was ignoring is simply not reproduced. Fix the source CSS, then reformat.
