Shadows are a useful design tool that can be used to add shadow effects around an element's frame. The box-shadow property gives the ability to add multiple shadow effects separated by commas. A box-shadow is usually described by X and Y offsets relative to the element, blur and spread radius, and color.
X offset => Positive value creates a shadow to the right and negative value creates a shadow to the left.
Y offset => Positive value creates a shadow below the element and a negative value above the element.
Blur => The bigger the value the bigger and lighter the shadow.
Color => Color of the shadow.
In the above image, the shadow is
100px to the right (X axis)
10px below the element (Y axis)
A blur radius of 10px
The color is #e453d8
