CSS Box Shadow Generator

What is this?

A visual CSS Box Shadow Generator that allows web developers to design realistic, multi-layered elevation shadows and glow effects. Features interactive sliders for X/Y offset, blur, spread, shadow color, alpha opacity, inner/inset toggles, multi-layer shadow stacking, preset libraries, and Tailwind CSS utility code generation.

Key Features & Concepts

• Multi-Layer Shadow Stacking: Stack multiple shadow layers to achieve smooth, natural, realistic elevation physics
• Precision Controls: Fine-tune Horizontal Offset (X), Vertical Offset (Y), Blur Radius, Spread Radius, Shadow Color, and Opacity
• Inset / Inner Shadow Toggle: Create pressed, carved, or inner-glow UI container effects
• Interactive Canvas Preview: Test shadow effects on custom background colors, card shapes, and element sizes
• Preset Elevation Library: Material Design 1-5, Soft Modern Elevation, Neon Glow, Floating Glass, and Cutout Inset presets
• CSS & Tailwind Code Generation: Output standard `box-shadow` CSS properties and Tailwind arbitrary shadow utilities (`shadow-[...]`)
• One-Click Copying: Quickly copy shadow CSS declarations to your clipboard
• 100% Client-Side Engine: Fast, smooth 60fps slider updates powered by local browser CSS rendering

How to Use

1. Adjust Horizontal (X) and Vertical (Y) offsets to position the shadow light source.
2. Modify Blur Radius to control shadow softness and Spread Radius to expand or contract shadow boundaries.
3. Set shadow color and opacity using the color picker and alpha slider.
4. Click "+ Add Layer" to stack multiple soft shadow layers for high-end modern UI depth.
5. Copy the generated `box-shadow` CSS property or Tailwind CSS class.

Common Use Cases

• Web Developers styling interactive cards, modals, and buttons
• UI/UX Designers experimenting with shadow physics and elevation depth systems
• Tailwind CSS users generating custom arbitrary shadow utilities
