Shadows are essential in modern web design for creating depth and visual hierarchy. The CSS box-shadow property is your best ally to achieve this.

Basic Syntax

The basic syntax of box-shadow is:

box-shadow: offset-x offset-y blur-radius spread-radius color;
  • offset-x: Horizontal offset.
  • offset-y: Vertical offset.
  • blur-radius: How much the shadow behaves.
  • spread-radius: How much the shadow grows or shrinks.
  • color: The color of the shadow.

Creating Realism

For realistic shadows, avoid pure black (#000). Use dark colors with transparency, like rgba(0, 0, 0, 0.2).

Soft Shadows (Neumorphism, Glassmorphism)

Modern trends use multiple overlapping shadows to create softer, more natural effects.

/* Soft shadow example */
box-shadow: 
  0 4px 6px -1px rgba(0, 0, 0, 0.1), 
  0 2px 4px -1px rgba(0, 0, 0, 0.06);
