CSS Box Shadow Generator — Visual Shadow Editor

The CSS box-shadow property has several parameters, each affecting the shadow appearance.

Parameters:

• offset-x: horizontal shadow offset (can be negative)
• offset-y: vertical shadow offset (can be negative)
• blur-radius: blur radius (larger values = softer shadow)
• spread-radius: expands or contracts the shadow (can be negative)
• color: shadow color (supports rgba for transparency)
• inset: keyword for creating an inner shadow

CSS allows adding multiple shadows to one element separated by commas, enabling complex visual effects.

Examples:

• Material Design Material Design uses 2 shadows for realistic depth
• Neumorphism combines light and dark shadows for a 3D effect
• Paper effect is created with 3-4 shadow layers at different blur levels
• Glow effects Neon effects use multiple same-color shadows

Box-shadow is widely used to create visual hierarchy and depth in user interfaces.

Examples:

• E-commerce product cards with light shadows
• Modal windows with deep shadows for focus
• Dropdown Dropdown menus with soft shadows for separation
• Hover Hover effects with animated shadows for interactivity
• Sidebar Side panels with subtle shadows for structure
• Toast notifications Notification toasts with soft shadows for visibility

Shadows add depth to buttons and other interactive elements, improving UX and visual feedback.

Examples:

• Raised buttons Raised buttons with shadows for 3D effect
• Pressed state with inner shadow for clicked button
• Floating action buttons Floating action buttons with strong shadows
• Toggle switches Input fields with light shadows
• Form inputs with inner shadow, toggle switches with inset shadows
• Icon buttons with hover shadows, interactive cards with hover transitions

Neumorphism is a popular design trend using soft shadows to create pseudo-3D interfaces.

Examples:

• Soft UI Raised elements with dual shadows (dark and light)
• Pressed state with inverted inner shadows
• Concave Concave surfaces with inner light-dark shadows
• Floating Flat elements with soft outer shadows
• Toggle switches and progress bars in neumorphic style
• Cards Cards with subtle neumorphic shadows

Box-shadow is GPU-rendered with minimal performance impact. However, very large blur values (over 50px) or many shadowed elements may slow rendering on low-end devices.

Technically no limit, but 2-4 shadows are recommended for performance. Our generator supports up to 5 layers.

Inner shadow (inset) creates a shadow inside the element for a sunken effect. Used for pressed button states, input fields, and neumorphic concave surfaces.

Use offset-x or offset-y with negative spread. Example: box-shadow: 0 4px 0 -2px rgba(0,0,0,0.2) creates a bottom-only shadow.

Yes, box-shadow fully supports CSS transitions and animations. However, animating blur-radius can be resource-intensive — it is better to animate shadow opacity or use transform: translateY() instead of changing offset-y.

All modern browsers support box-shadow since 2009 without prefixes. Covers 99%+ of users including mobile.
