When should I use inset shadows?

Inset shadows render inside the element's border, useful for pressed-button states, inner depth on input fields, or vignette effects on images.

How do I make shadows look natural?

Use two or three stacked shadows: a tight, darker one for contact depth plus a large, faint one for ambient lift. Avoid pure black — tint shadows toward your background color.

About this tool

The Box Shadow Generator builds layered CSS shadows with a visual preview. Control horizontal and vertical offset, blur radius, spread, color, opacity, and inset mode — then copy the resulting box-shadow declaration.

Layering multiple soft shadows creates more realistic depth than a single hard shadow. The tool shows each layer's contribution so you can fine-tune realistic elevation for cards, modals, and buttons.

How to use

1Drag the Blur Radius and Alpha Opacity sliders.
2Preview the shadow live on the sample surface.
3Copy the generated box-shadow CSS into your stylesheet.

Frequently asked questions

Blur softens the shadow's edges, while spread expands or contracts the shadow's overall size. A large blur with zero spread gives a soft glow; adding spread makes it denser.
