Frequently asked questions

What is a CSS box-shadow?

box-shadow draws one or more shadows behind or inside an element. Each layer has horizontal and vertical offset, blur, spread, color, and an optional inset keyword.

How do multiple shadow layers work?

The first layer is drawn on top. Add up to 8 layers for stacked depth — for example a tight contact shadow plus a softer lift. Reorder layers to change which one sits in front.

What is the difference between inset and outer shadows?

An outer shadow falls outside the box. Inset draws the shadow inside the border, useful for pressed buttons and wells.

Can I copy HEX, RGB, or HSL?

Yes. Switch the color format to change both the color field and the generated CSS. Opacity below 100% uses 8-digit hex, rgba(), or hsla().

Is the Box Shadow Generator free?

Yes. It runs in your browser with no signup. Colors and CSS stay on your device.
