Neumorphism CSS Effect Tutorial - How to Create Neumorphism

Learn how to create the neumorphism CSS effect. Soft extruded UI, dual opposing shadows, no borders.

AI agents add a single box-shadow and call it neumorphism. The real effect needs two opposing shadows (one light, one dark) derived from the background color, elements whose background exactly matches the parent surface, zero visible borders, and proper inset shadows for pressed states. Agents get every one of these wrong.

Copy and paste this neumorphism CSS code into your AI coding agent (Claude, ChatGPT, Cursor) for instant implementation.

Neumorphism

AI agents add a single box-shadow and call it neumorphism. The real effect needs two opposing shadows (one light, one dark) derived from the background color, elements whose background exactly matches the parent surface, zero visible borders, and proper inset shadows for pressed states. Agents get every one of these wrong.

Examples

Raised
Element extruded from the surface. Two opposing shadows create the 3D illusion — no borders needed.
Pressed
Same shadows but inset. The element sinks into the surface instead of rising from it.
