What Is a Box Shadow Generator?

The `box-shadow` syntax is `offset-x offset-y blur spread color`, optionally prefixed with `inset` and stackable with commas. Each layer adds depth: a tight shadow close to the element grounds it, a softer shadow further away simulates ambient light. Designers routinely stack two or three layers — a sharp short shadow plus a soft long one — for realistic Material-style depth.

This generator gives you sliders for each parameter and a live preview of the result. Add multiple layers with the + button, each with its own controls. The generated CSS appears below the preview, ready to copy into your component or stylesheet.

Frequently Asked Questions

What does box-shadow syntax mean?
box-shadow: offset-x offset-y blur spread color. Inset for inner shadow. Multiple shadows: comma-separate.
How do I create a soft shadow?
Low offset (2-4px), high blur (10-20px), zero or negative spread. Light gray (rgba(0,0,0,0.1)) for subtle effect.
Can I have multiple shadows?
Yes — the generator supports adding multiple layers, each with its own offset, blur, spread and colour.
