CSS Box Shadow Generator

How to Use the Free CSS Box Shadow Generator

A CSS box shadow generator is an indispensable utility for frontend developers and UI designers seeking to craft modern, layered depth effects on web cards, buttons, modals, and containers. The CSS box-shadow property allows you to cast soft or sharp drop shadows from an element's frame.

Understanding Box Shadow Parameters

Fine-tuning shadow aesthetics relies on mastering six core parameters:

• Horizontal Offset (X): Moves the shadow left (negative value) or right (positive value).
• Vertical Offset (Y): Moves the shadow up (negative value) or down (positive value).
• Blur Radius: Controls the softness or sharpness of the shadow edge. Higher values create diffused ambient drop shadows.
• Spread Radius: Expands or contracts the shadow footprint relative to the element size.
• Color & Opacity: Sets shadow color using RGBA or HEX with transparency for natural light blend.
• Inset: Switches the shadow position from outside the box to an inner drop shadow inside the element boundary.
