How CSS Beautifier Works
The beautifier reads your CSS and rebuilds it with one selector or declaration per line, indenting nested content after every opening brace. Strings and comments are left untouched so quoted content like content: "→" is never altered.
How to Use This Tool
- Paste your CSS — minified or otherwise — into the input box.
- Select Beautify CSS.
- Copy the formatted result from the output box.
Example
Input: .btn{color:#fff;background:#4f46e5}
Output:
.btn {
color: #fff;
background: #4f46e5
}Helpful Tips
- Run the result through the CSS Minifier before shipping to production — keep the readable version for editing and the minified version for the live site.
- Nested at-rules like
@mediaare indented the same way as regular selectors.
Frequently Asked Questions
Will this change any of my CSS values?
No, only whitespace and line breaks are changed — every selector, property and value stays exactly as written.
Does it support SCSS or LESS syntax?
It's built for standard CSS. Most simple SCSS/LESS still formats reasonably since the tool works on braces and semicolons, but nested preprocessor-only syntax isn't specifically validated.
Is my CSS uploaded anywhere?
No, formatting happens entirely in your browser.
This tool runs entirely in your browser. Your input is not uploaded to any server.
