Free CSS Box Shadow & Glassmorphism Generator — Visual CSS Tool

Design Smooth CSS Box Shadows & Frosted Glass Effects. Visual editor for modern CSS box-shadows, soft elevations, and frosted glassmorphism cards with one-click CSS copy.

What is Box Shadow and what does it do?

The CSS Box Shadow Generator is an interactive visual styling tool that allows frontend developers and web designers to create, customize, and stack multiple CSS box shadows with real-time preview.

Featuring intuitive sliders for horizontal offset, vertical offset, blur radius, spread radius, color, and inset mode, it outputs cross-browser compatible, production-ready CSS and Tailwind CSS classes instantly.

  • Design single or multi-layered CSS box shadows with granular control over X/Y offset, blur, spread, and opacity.
  • Toggle between outer drop shadow and inner inset shadow effects.
  • Live preview card with customizable background colors to test shadows on light, dark, and vibrant surfaces.
  • Generates clean standard CSS (box-shadow) and custom Tailwind CSS utility configurations with one-click copy.
  • Preset library of popular modern shadow styles: subtle elevations, neomorphic soft UI, float cards, and neon glows.

How does Box Shadow work?

Slider values and color picker inputs are bound to reactive state properties that compute the CSS box-shadow property string. Multi-layer shadows are joined with comma separation.

The computed shadow rule is applied directly to the style attribute of the live preview element, and the equivalent CSS/Tailwind snippet is formatted in the output code block.

100% private: all processing happens locally in your browser using client-side WebAssembly, HTML5 Canvas, and modern Web APIs. Your files are never uploaded to any server.
