What's the difference between blur and spread in box-shadow?

Blur controls the softness of the shadow's edges — a higher blur value creates a softer, more diffused shadow. Spread controls how far the shadow extends beyond the element's boundaries — a positive spread makes the shadow larger, and a negative spread makes it smaller.

How do I create a realistic shadow?

Use multiple shadow layers with different offsets and blur values. A common pattern is a sharp, close shadow with low blur and offset for definition, combined with a softer, more distant shadow with higher blur for ambient depth. Keep opacity low (0.1-0.3) for natural results.

What is an inset shadow?

An inset shadow appears inside the element's boundary instead of outside it. This creates a recessed or pressed-in effect, commonly used for input fields, well containers, and active button states. Toggle the inset option to switch between outer and inner shadows.

Can I add multiple shadows to one element?

Yes, the generator supports multiple shadow layers. Each layer has its own offset, blur, spread, color, and inset settings. Multiple layers create more realistic depth than a single heavy shadow.

Does the generated CSS work in all browsers?

Yes, the box-shadow property is supported in all modern browsers including Chrome, Firefox, Safari, Edge, and mobile browsers. The generated code uses standard syntax without vendor prefixes.
