Generate the soft-UI look
Neumorphism is the soft, extruded style where an element appears to be pressed out of, or pushed into, the background surface it sits on, an illusion created entirely with a carefully matched pair of shadows, one light and one dark. This generator produces that CSS from a base colour and a few shadow settings, handling the paired shadows that make the effect actually work rather than leaving you to guess at two opposing shadow values by hand.
Why it needs two shadows
The whole illusion of an element gently rising from the surface comes from simulating light striking it from a single consistent direction: a light-coloured shadow falls on the top-left and a darker shadow on the bottom-right, or the two swap over for a pressed-in look instead. Both shadows must be derived from the background colour itself, which is exactly why neumorphism only works convincingly on a solid, mid-tone background where there is room to go both lighter and darker.
Copy the CSS
It runs entirely in your browser, so nothing you enter is uploaded and the generated code is yours to paste straight into a project. Because it works client-side, you can iterate freely, regenerating as often as you like without a round trip to any server.

Frequently Asked Questions
What is neumorphism?
A soft-UI style where elements look extruded from or pressed into the background, created with a paired light and dark shadow.
Why does it use two shadows?
To simulate light from one direction: a light shadow on one side and a dark one on the opposite side make the element appear to rise from or sink into the surface.
Why does it need a mid-tone background?
Because both shadows derive from the background colour. On pure white or black there is no room for a lighter or darker shadow, so the effect fails.
Is there an accessibility caveat?
Yes. The low contrast that gives neumorphism its softness can make elements hard to distinguish, so use it carefully where clarity matters.
Is my input uploaded?
No. The generator runs entirely in your browser.
