Multi-layer box-shadow builder: stack shadows with offset, blur, spread, and opacity, preview on a background, then copy production-ready CSS.
Adam Mocarski's shadowLab is a focused editor for layered box shadows. Add or tune each layer with X/Y offset, blur, spread, opacity, and color, switch presets and backgrounds to see depth in context, and copy the CSS when the stack feels right. A clean reference for elevation, cards, and subtle UI depth without guessing in DevTools.
