Turn compressed or messy CSS into indented rules so reviews and diffs are readable. Formatting does not change cascade — only whitespace and structure.
Example starts as a minified card snippet — Format restores indentation.
Input
.card{display:flex;padding:1.5rem;border-radius:.5rem;background:#fff}.card h2{font-size:1.25rem;font-weight:600;margin:0 0 .5rem}
Output
.card {
display: flex;
padding: 1.5rem;
border-radius: 0.5rem;
background: #fff;
}
Format before code review; minify only for production bundles.
