What Is a CSS Formatter?

A CSS formatter takes minified or messily-written CSS and rewrites it with each selector, property and closing brace on its own properly indented line, making a stylesheet's rules easy to scan and edit.

It's especially useful when working with third-party or minified CSS that needs to be read, debugged, or partially copied into a project in a readable form.
