The box shadow property in CSS adds a shadow to any element in HTML. A box shadow is described by X and Y offsets relative to the element, blur and spread radius, and color.
/* offset-x | offset-y | blur-radius | color */
box-shadow: 10px 5px 5px black;
/* inset | offset-x | offset-y | color */
box-shadow: inset 5em 1em gold; If a border-radius is specified on the element, the box-shadow will take the same rounded corners as the element.
If used multiple box-shadow‘s, the first one will be on top.
box-shadow: 3px 3px red, -1em 0 .4em blue; This is a box with multiple box-shadows around it.
