Neumorphism evolved from Skeuomorphism, a design movement that believed in creating life-like objects by imitating them.
It all started with Apple’s design philosophy of creating symbols that resembled real-life objects so that the users could connect with them easily.
It went a step ahead with Neumorphism where soft UI elements and tender-looking designs evolved to provide the users a more simple and effective experience.
The main characteristics of Neumorphism are the use of simple and flat lines and the heavy use of box shadow to create buttons in the same color as the background. At times, two shadows are used to make them look like they are appearing from the back.
