Why use a CSS formatter?

CSS files grow organically and often end up with inconsistent formatting — some properties on one line, others on multiple, media queries mixed with rules, and vendor prefixes scattered unpredictably. QuickKit's CSS formatter uses Prettier's PostCSS plugin, which supports standard CSS as well as SCSS and Less syntax. It formats each rule block onto its own line, adds consistent spacing around values, and normalizes selector grouping. Paste minified CSS from a build output, unformatted styles copy-pasted from a tutorial, or a Tailwind @apply block and get back clean, readable CSS that your team's style guide would approve.
