About Box Shadow Generator
What this tool does
A visual editor for the CSS box-shadow property. Drag sliders for horizontal offset, vertical offset, blur radius, spread radius, color, alpha, and inset. Stack multiple shadows to build layered depth (Material-style elevation, Neumorphism, Tailwind-like shadow-lg).
When to use it
- Prototyping a card, button, or modal elevation before committing CSS
- Building layered / Neumorphic shadows that would be painful to write by hand
- Reverse-engineering a shadow from a mockup
- Teaching what each shadow parameter actually does
Frequently asked questions
Yes — click Add layer to stack shadows; each layer has its own offset, blur, spread and color.
Yes. Toggle inset per layer to invert the shadow so it appears inside the element.
No — modern browsers all support unprefixed `box-shadow`. Add prefixes manually if you must support pre-2013 browsers.
A live box in the centre updates as you drag sliders. Change its background color to preview on light or dark surfaces.
