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