About this tool

box-shadow takes x-offset, y-offset, blur, spread, color and an optional inset keyword. Getting the feel right by typing numbers is slow; this tool renders every slider move live on a sample card and emits the exact CSS line, including rgba() with your chosen opacity.

FAQ

When should I use inset?
For pressed/engraved UI (wells, pressed buttons). Outer shadows lift; inset pushes in.
Blur vs spread?
Blur softens edges; spread grows the whole shadow footprint.
