CSS Box Shadow Generator: a worked example

You want a soft, modern "lifted card" shadow that looks subtle on white but is still visible, without trial-and-error in DevTools.

Shadow controls

X 0 · Y 10 · Blur 25 · Spread -5 · Color rgba(0,0,0,0.25) · Inset off
CSS Box Shadow Generator produces

Generated declaration

box-shadow: 0 10px 25px -5px rgba(0, 0, 0, 0.25);

The negative spread (-5) shrinks the shadow so it stays tucked under the element instead of leaking out the sides, while the 25px blur with low-alpha black reads as a soft ambient lift rather than a hard drop. The live preview shows the result on the actual background colour you choose, so you tune perception, not numbers in isolation.

Frequently asked questions

Can I stack multiple shadows?

Yes. Layering multiple shadows with different offsets and blurs creates more realistic depth effects.

What's an inset shadow?

An inset shadow appears inside the element rather than outside, creating a pressed-in or recessed look.

Do box shadows affect layout?

No. Shadows are purely visual and don't change the element's size or position in the layout.
