How to use it
Each layer is one shadow. Move it with Offset X and Y, soften it with Blur, and grow or shrink it with Spread. Tick Inset to put the shadow inside the box. Add more layers and the browser draws them all, the first layer on top. Copy the CSS when it looks right.
Tips for natural shadows
Real shadows fall downward, so keep Offset X near zero and Y positive. Low opacity (5–20%) looks more natural than solid black. Stacking several soft layers with growing blur and offset, like the Layered preset, gives smooth depth that a single shadow can’t.
