css box shadow generator
Smooth CSS Box Shadow Generator
A single shadow looks flat. Stack two or three layers — a tight dark shadow close to the edge, a soft wide one further out — and you get the smooth, realistic 3D depth used in real interfaces.

Why layered box shadows look more realistic
A single css box shadow tool call reads as flat because real light casts more than one edge: a crisp, close, dark shadow where the object nearly touches the surface, and a soft, wide, faint one where light wraps around it. Combining both is the layered box shadow css technique behind most modern card and button depth.
Using the css smooth drop shadow tool
Set your first layer tight and dark, click "Add layered shadow" for a second pass with a larger blur and lower opacity, and the generator combines every layer into one comma-separated box-shadow declaration ready to paste.
