Why Format CSS Code

CSS formatting improves readability by adding consistent indentation, line breaks and spacing around selectors, declarations and nested structures. Unlike minification, formatting is intended for people rather than reducing production file size. Clean formatting can make it easier to spot missing braces, duplicate declarations and rules that belong to the wrong selector. A formatter generally preserves the meaning of valid CSS, but it cannot guarantee that malformed code will behave as intended. After formatting a stylesheet, review unusual constructs such as custom properties, embedded data URLs, vendor-specific syntax or generated code if the source is complex. For production delivery, developers often keep a readable source version and create a separate minified build. Formatting is therefore most useful during editing, code review, debugging and maintenance rather than as a performance optimization by itself.
