  4. Copy the generated CSS.

About this tool

A well-tuned shadow lifts cards and buttons off the page. The four values — horizontal offset, vertical offset, blur and spread — are hard to guess by hand, so the generator lets you dial them in visually and copy the exact rule.

When to use it: giving cards and buttons depth without guessing CSS values.

Frequently asked questions

What is “spread”?
Spread grows (positive) or shrinks (negative) the shadow size before blur is applied. Positive spread makes a shadow look bolder.
What does inset do?
It draws the shadow inside the element instead of around it — useful for pressed-in effects and form fields.
How do I make a soft, modern shadow?
Use a low-opacity dark color, a large blur and a small vertical offset — for example 0 10px 25px with about 15% opacity reads soft and natural.
Can I layer several shadows?
Yes — in CSS you can comma-separate multiple box-shadow values; design each layer here and join them by hand for depth.
Does a big blur hurt performance?
Slightly on very low-end devices when many large shadows animate at once; static shadows like the ones you copy here are fine.
Should shadows be pure black?
Rarely — a low-opacity shade of your background’s hue looks more natural than harsh #000.
