Does formatting change how the CSS styles my page?
No. CSS formatting only changes whitespace. The selectors, properties, and values remain identical, so the visual output is unchanged.
CSS Formatter takes minified, compressed, or inconsistently-indented CSS and transforms it into clean, readable code with proper indentation and line breaks. Developers use this when debugging third-party minified CSS, cleaning up auto-generated styles from UI libraries, or preparing CSS snippets for documentation and code reviews.
CSS formatting parses the stylesheet and reformats each rule block with each property on its own line, indented by 2 spaces. Selectors, properties, and values are preserved exactly — only whitespace structure is changed.
