Material Design's elevation system uses soft, downward, low-opacity shadows to suggest a card floating slightly above the page — no harsh edges, no strong offset, just enough blur to read as depth rather than a hard-edged drop shadow.
shadowPreset: elevated · offsetX: 0 · offsetY: 4 · shadowBlur: 12 · spread: 0 · shadowColor: #000000 · shadowOpacity: 0.15 · isInset: falseMaterial elevation shadows use a small vertical offset with a larger blur radius — the blur does most of the work of suggesting depth, not a large offset, which would look like a heavier drop shadow instead.
Typically low, around 0.1-0.2 — high-opacity shadows read as harsh drop shadows rather than the soft, subtle elevation Material Design aims for.
Increase both the offset and blur together (e.g. offset 8px, blur 24px) to suggest a card floating further above the page — this generator's sliders let you dial that in live.
