Minified stylesheets and inline style blocks copied from a browser's dev tools are usually one dense line, making it hard to review or edit them. This CSS formatter parses your stylesheet and reformats it with consistent indentation, one property per line, and properly nested media queries and rule blocks. It's useful for frontend developers reviewing a minified stylesheet, students learning CSS structure, and anyone debugging a style conflict who needs to actually read the rules clearly. The formatter preserves selector specificity and property order exactly, so nothing about how the CSS applies is changed, only its readability. Since formatting happens entirely in your browser, your stylesheet is never uploaded to a server, and there's no signup required. Paste your CSS below to see it beautifully formatted instantly.

Frequently asked questions
What does a CSS formatter do?
It rewrites minified or single-line CSS with proper indentation and one property per line, making rules and selectors easy to read and edit.
Does formatting change how the styles apply?
No, only whitespace and line breaks are adjusted - selector specificity, property order, and computed styles remain exactly the same.
Can it handle nested media queries?
Yes, @media rules and their nested selectors are indented clearly to show the containment relationship.
Does it support CSS variables and calc()?
Yes, custom properties (--variable-name) and calc() expressions are formatted correctly without altering their values.
Is my stylesheet uploaded to a server to format it?
No, formatting happens entirely in your browser using client-side JavaScript, so your CSS is never sent anywhere.
Can this tool also minify CSS?
Yes, you can toggle to a minified view of the same stylesheet for production deployment.
Does it work with SCSS or LESS syntax?
It's optimized for standard CSS syntax; SCSS or LESS-specific features like nesting and mixins may not format ideally since they aren't valid plain CSS.
