CSS Multi-Layer Box Shadow Generator
Design a layered box-shadow from one set of controls
Set an offset, blur, spread, colour and layer count, watch a live preview, and copy a multi-layer box-shadow declaration built the way designers stack shadows for real depth. Everything renders in your own browser.
box-shadow: 0px 4px 6px -1px rgba(23, 33, 28, 0.3), 0px 8px 12px -2px rgba(23, 33, 28, 0.26), 0px 12px 18px -2px rgba(23, 33, 28, 0.22), 0px 16px 24px -3px rgba(23, 33, 28, 0.18), 0px 20px 30px -4px rgba(23, 33, 28, 0.14);

What this tool does
A single box-shadow layer tends to look like flat fog; real elevation comes from stacking several layers that shrink and fade as they approach the element, the way ambient light falls off. This tool takes one set of offset, blur, spread and colour controls plus a layer count, and derives that many progressively tighter, more opaque layers automatically, so you get a convincing stacked shadow without hand-tuning each one.
How to use it
- Choose how many layers to generate.
- Set the offset, blur, spread, colour and opacity for the base layer.
- Copy the generated multi-layer box-shadow declaration.

Frequently asked questions
- Is anything uploaded?
- No. The preview is a CSS shadow painted by your browser and the declaration is assembled in the page.
- How are the individual layers derived?
- Each layer scales the offset, blur and spread down toward the element and increases in opacity as it gets closer, which is the same shrink-and-fade pattern used in hand-built elevation systems.
- Why cap the layer count?
- Past five or six layers the visual difference becomes negligible while the CSS keeps growing, so the control is capped to keep the output easy to read and paste.
