CSS Box Shadow Generator - Visual Shadow Editor

Design CSS box shadows visually with intuitive sliders and see changes in real time. Adjust offset, blur, spread, color, and opacity to create anything from subtle elevation effects to dramatic drop shadows. Copy the CSS code with one click.

The CSS box-shadow property accepts values for horizontal offset, vertical offset, blur radius, spread radius, and color. Positive offsets move the shadow right and down. The blur radius controls softness, while spread expands or contracts the shadow size. The inset keyword creates inner shadows.

UI designers use box shadows to create depth and visual hierarchy in card layouts, modal dialogs, dropdown menus, floating action buttons, and navigation bars. Material Design and modern UI frameworks rely heavily on shadow layering to indicate elevation levels.

For modern, realistic shadows, use rgba colors with low opacity (0.1-0.2) and large blur values. Layer multiple shadows for depth: a tight shadow for the edge and a diffuse shadow for ambient light. Avoid pure black shadows - use a darker shade of your background color for a more natural look.

While design tools like Figma and Sketch have shadow editors, they export platform-specific values that may not translate perfectly to CSS. This generator produces exact CSS syntax ready for production. Pair it with our CSS Gradient Generator for complete visual styling of your UI components.

  5. 05Copy the generated CSS code to use in your project

Box Shadow Design Tips

Box shadows add depth and visual hierarchy to web elements. For a subtle, modern look, use soft shadows with large blur radius and low opacity (e.g., 0 4px 16px rgba(0,0,0,0.1)). Layer multiple shadows for more realistic depth. Avoid harsh, high-contrast shadows - they look dated. Inset shadows create a pressed or recessed effect, useful for input fields and active buttons.

When to Use the CSS Box Shadow Generator

Use this generator when designing cards, modals, dropdown menus, navigation bars, or any UI element that needs depth. Material Design and modern flat design both rely on shadows to create visual hierarchy. Instead of guessing CSS values, adjust sliders visually and copy the exact code you need.

Common Use Cases

  • Creating elevation effects for card components and modal dialogs
  • Designing button hover and active states with shadow transitions → CSS Gradient Generator
  • Adding depth to navigation bars and sticky headers
  • Building neumorphism and glassmorphism UI effects with layered shadows → Color Palette Generator

Expert Tips

  • Use rgba() with low opacity (0.08-0.15) instead of pure black for natural-looking shadows
  • Layer two shadows - a tight one for edge definition and a larger diffuse one for ambient depth
  • Match your shadow color to a darker shade of the background for more natural results than using black

Frequently Asked Questions

What does each box-shadow value control?→
The box-shadow property takes: horizontal offset (positive = right), vertical offset (positive = down), blur radius (softness), spread radius (size expansion/contraction), and color. Adding 'inset' creates an inner shadow. Example: box-shadow: 4px 4px 8px 0px rgba(0,0,0,0.2).
Can I add multiple shadows to one element?→
Yes, separate multiple shadow values with commas. Layered shadows create more realistic depth effects. A common technique is combining a tight, subtle shadow (edge definition) with a larger, diffuse shadow (ambient light). Example: box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 4px 12px rgba(0,0,0,0.08).
What is an inset shadow?→
An inset shadow appears inside the element instead of outside it. It creates a pressed or recessed effect, commonly used for input fields (to make them look carved in), active button states, and inner containers. Add the 'inset' keyword at the beginning of your shadow value.
