CSS Beautifier

What is the CSS Beautifier?

The CSS Beautifier reformats compact or minified CSS so it is easier to read. CSS controls the layout, colours, fonts, and spacing of web pages. When CSS is minified, all whitespace is removed and rules run together on one line. This tool runs in your browser and adds spacing around selectors and braces so you can scan the rules more easily.

How to Use the CSS Beautifier

1. Open the CSS Beautifier page.
2. Paste your CSS into the workspace box.
3. Click Process to reformat it.
4. Read the result in the Result panel.
5. Click Copy to copy the formatted CSS back into your stylesheet or editor.

Worked Example

Observed run: input body{margin:0;padding:0;color:#333}h1{font-size:24px} returned body { margin:0; padding:0; color:#333 } h1 { font-size:24px }. The tool added a space before each opening brace and after each closing brace, and a space after each opening brace, but it kept each rule on one line. The declarations stayed separated by semicolons with no line breaks or indentation.

Limitations

• Formatting is minimal. It adds spaces around braces but does not put each declaration on its own line or indent nested rules.
• There are no options for indent size, line breaks, or sorting properties.
• It does not validate CSS or report syntax errors. A missing brace or semicolon will pass through unchanged.
• It does not minify, autoprefix, or optimise CSS. It only adds spacing.
• Media queries and complex selectors get the same light spacing treatment, so very long rules can still be hard to read.

Frequently Asked Questions

Does the CSS Beautifier put each property on its own line?

No. In the observed run it kept each rule on one line and only added spaces around braces. For multi-line formatting, use a full code formatter in your editor.

Will it fix broken CSS?

No. It does not validate or repair CSS. Fix missing braces and semicolons yourself before or after formatting.

Does it change what the CSS does?

No. It only adds whitespace, which does not change how browsers apply the rules.

Can I use it for SCSS or Less?

It is designed for plain CSS. Nested SCSS or Less syntax may not format as expected, so test the output before using it.
