Balanced braces

3 rules · 3 selectors · 212 chars (min 210)

Light formatter — not Prettier. Adds indentation around braces and semicolons. Minify strips comments and whitespace. Validate only checks brace balance; not a full CSS parser.

How it works

1

Paste or import CSS

Paste CSS text or import a .css file up to 5 MB. Unbalanced braces are flagged live.

2

Format or minify

Format adds readable indentation (2 or 4 spaces). Optionally sort properties alphabetically inside each rule. Minify removes comments and extra spaces.

3

Copy or download

Click Format or Minify (counts toward the daily limit). Copy the result or download formatted.css.

Why format CSS?

Minified production CSS is hard to read during debugging. Pretty-printing restores structure so you can inspect rules copied from DevTools or legacy stylesheets.

Why use this tool

  • Pretty-print with 2 or 4 space indent
  • Minify with comment removal
  • Sort properties per rule
  • Brace validation
  • Import .css files
  • Unlimited — no daily cap

Questions

What does CSS Formatter do?

It indents rules for readability or minifies CSS by removing comments and whitespace. It checks balanced { } braces.

Will formatting break my CSS?

Only whitespace changes in most cases. Always review minified output — complex selectors and strings are not fully parsed.

What does Sort properties do?

Alphabetically orders declarations inside each rule block before formatting — handy for consistent diffs.

Does it support SCSS or LESS?

Simple CSS works best. Nesting and variables in preprocessors may not format correctly.

Is my CSS sent to a server?

No. Processing runs entirely in this tab.

Is there a daily limit?

No. This tool has no daily cap.
