Why Format CSS?
Formatted CSS is dramatically easier to read, debug, and maintain. Each selector on its own line with properly indented properties makes it fast to scan stylesheets and spot inheritance or specificity issues.
When working with build tools that output minified CSS, or debugging production styles, this formatter restores readability instantly. For general multi-language formatting, the Code Formatter covers CSS alongside JSON, HTML, SQL, and more.
CSS Minification Best Practices
Always keep a formatted development copy and minify only for production. The minifier removes comments — if you rely on license comments, add them back after minification or use a build tool that preserves them.
