About this tool

Generate CSS box-shadows visually

Dial in the offset, blur, spread and color with sliders and copy the ready box-shadow. A live preview shows how it lands on light and dark backgrounds.

Recipes

  • Subtle card — small offset, large blur, low-opacity color (0 4px 12px rgba(0,0,0,.08)).
  • Elevated/floating — bigger offset + blur for a lifted feel.
  • Inset — toggle inset for pressed buttons or inner depth.

Stack several shadows (comma-separated) for layered, realistic depth. Box-shadow paints outside the box model, so it never shifts your layout.

Frequently asked questions

Common questions about the CSS Box Shadow Generator.

How do I create a CSS box-shadow?

Drag the horizontal/vertical offset, blur, spread and color controls; the live `box-shadow` value updates and you copy it into your CSS.

How do I make a soft, subtle shadow?

Use a small offset, a larger blur radius, and a low-opacity color such as rgba(0,0,0,0.1).

What is an inset shadow?

Inset draws the shadow inside the element instead of outside — great for pressed buttons or inner depth. Toggle the inset option.

Can I stack multiple shadows?

Yes. CSS supports comma-separated box-shadows, so you can layer several for richer depth.

Does box-shadow change my layout?

No — box-shadow is painted outside the box model, so it never pushes other elements around.
