What is a CSS box shadow?

A CSS box shadow is a visual effect that adds a shadow behind (or inside) an HTML element using the box-shadow property. It accepts values for horizontal offset, vertical offset, blur radius, spread radius, and color.

Can I add multiple shadow layers?

Yes! CSS supports comma-separated multiple shadows on a single element. This tool lets you add, toggle, and tune each layer independently, then outputs all layers as a single clean CSS value.

What is an inset shadow?

An inset shadow is drawn inside the element's border instead of outside it. It's useful for creating pressed/sunken effects, inner glows, or carved-in UI elements. Toggle the Inset switch on any layer to use it.

Does this tool work without an account or API?

Yes — completely free, no login required, no API calls. All shadow calculations happen entirely in your browser.
