About CSS

CSS (Cascading Style Sheets) is a style sheet language used for describing the presentation of a document written in HTML or XML. CSS describes how elements should be rendered on screen, on paper, in speech, or on other media. It's one of the cornerstone technologies of the World Wide Web, alongside HTML and JavaScript.

Frequently Asked Questions

What is CSS formatting?

CSS formatting, also known as "pretty printing," adds proper indentation, line breaks, and spacing to make CSS code more readable. It transforms compressed CSS into a structured, easy-to-read format.

What does minifying CSS do?

Minifying CSS removes all unnecessary whitespace, line breaks, and comments to create the smallest possible file size. This reduces bandwidth usage and improves website loading speed.

Is my CSS code safe to use with this tool?

Yes, this CSS formatter runs entirely in your browser. Your code is never sent to our servers or stored anywhere. All processing happens locally on your device for maximum privacy and security.

What happens if my CSS has syntax errors?

The tool will attempt to format your CSS even with minor syntax errors. However, major syntax errors may prevent proper formatting and will be highlighted for you to fix.

Can I format large CSS files?

Yes, but very large files may slow down your browser since processing happens client-side. For optimal performance, we recommend files under 5MB. Larger files should be processed in chunks.

What's the difference between CSS and Sass/SCSS?

CSS is the standard styling language for web pages. Sass/SCSS are CSS preprocessors that add features like variables, nesting, and mixins. They compile to regular CSS before being used in browsers.

Do I need to install anything to use this tool?

No installation required! This is a web-based tool that works in any modern browser. Simply paste your CSS and start formatting immediately.
