CSS Box Shadow Generator

Box Shadow Generator — Overview

The Box Shadow Generator gives you a visual interface for crafting CSS box-shadow declarations — one of the most powerful yet syntactically tricky CSS properties. A box shadow is defined by horizontal and vertical offsets, blur radius, spread radius, color (including opacity), and whether it appears outside or inside the element. Combining these five parameters can create anything from a subtle lifted card effect to a dramatic neon glow or a sharp hard shadow, but writing the values from memory and iterating blind is slow and error-prone. This tool lets you drag sliders, pick colors with an alpha channel, add multiple shadow layers, and see the result update live on a preview box. The generated CSS is always visible and one click away from your clipboard.

Common Use Cases

• Creating card and modal elevation effects for UI components
• Designing neon glow effects for dark-theme interfaces
• Generating soft, multi-layer shadows for a layered depth look
• Building inset shadows for pressed-button or embossed effects

How to Use This Tool

Use the sliders to set horizontal offset, vertical offset, blur, and spread values, then pick a shadow color and adjust its opacity. Toggle the Inset option for inner shadows. Add multiple shadow layers by clicking the plus button, then copy the final CSS declaration to use in your stylesheet.
