CSS Minifier
How It Works
- Toggle any checkbox → output updates instantly
- You can mix options (e.g., compact + no comments)
- Clean one-line-per-selector formatting when “Keep indentation” is ON
- Shows warning message + disables copy
- Auto-detect invalid CSS:
- Detects unbalanced
{},(),[] - Detects broken declarations (missing
:or;)
Note (Important)
This validator is lightweight, not a full parser. It catches:
- Broken
{}structure - Common syntax mistakes
