Frequently asked questions

Why layer multiple shadows?

One shadow rarely looks natural. Design systems like Material and Tailwind's default shadow use two or three layered shadows for realistic depth.

What's the difference between blur and spread?

Blur softens the edge (Gaussian falloff). Spread expands or contracts the shadow before blurring — useful for tighter, harder shadows.

When should I use inset?

Inset shadows draw inside the box — great for pressed-button effects, subtle inner glows, or 'inset' form fields.
