Shadow — CSS Shadow Effect Generator
A powerful CLI tool for generating, previewing, and managing CSS shadow effects. Supports box-shadow, text-shadow, drop-shadow, inset shadows, multi-layer effects, presets, random generation, animation keyframes, and export to CSS/JSON.
Prerequisites
- Python 3.8+
- Bash shell
Data Storage
All saved shadow presets and configurations are persisted in ~/.shadow/data.jsonl. Each line is a JSON object representing a shadow definition with its parameters.
Commands
Run all commands via the script at scripts/script.sh.

bash scripts/script.sh box [--x 0] [--y 4] [--blur 8] [--spread 0] [--color "rgba(0,0,0,0.2)"] [--name my-shadow] [--save]text
