About CSS Formatting
CSS (Cascading Style Sheets) controls the visual presentation of web pages. Well-formatted CSS with consistent indentation and spacing is easier to maintain, review in pull requests, and debug when styles break unexpectedly. This tool instantly beautifies or minifies your CSS.
When to Minify CSS
Minified CSS loads faster because it removes all unnecessary characters like spaces, newlines, and comments. This is standard practice for production deployments. Most build tools (Webpack, Vite, esbuild) minify CSS automatically, but this tool is useful for quick one-off minification or when working outside a build pipeline.
