What this developer tool does

Turn compressed or difficult CSS into a readable, searchable view. Format rules, filter by selector or property text, and inspect variables, media queries, colors, and important declarations.

Input protection → structural scan → selected transformation or analysis → validation → copy-ready output and measured statistics.

Processing is performed locally. Advanced language edge cases may require a full standards-based parser or project-specific toolchain.

Example

Input:

.button{background:#8b5cf6;color:white!important}@media(max-width:600px){.button{width:100%}}
Output: Run the included example to see a real result generated by this tool.

Tips for better output

  • Test converted code in the target browser or runtime.
  • Keep an original copy before applying automated changes.
  • Large inputs are processed locally; disable auto-run when editing very large files.
  • Pattern-based analysis may not cover every language edge case.
