Set the base color, shadow distance, blur and intensity, choose raised or inset, and copy the neumorphic box-shadow CSS.
A soft-UI style where elements appear extruded from or pressed into the background using paired light and dark shadows.
Neumorphism relies on the element and background being the same color so the shadows alone create the raised or inset look.
Use inset shadows so the light and dark highlights fall inside the element, making it look pressed into the surface.
