Frequently Asked Questions
What is CSS box-shadow?
`box-shadow` is a CSS property that adds shadow effects around an element. It supports offsets, blur radius, spread radius, color, and an optional `inset` keyword.
Why use multiple shadow layers?
Realistic elevation often uses 2+ layers: a tighter shadow for contact and a softer shadow for ambient light. Multiple layers look more natural.
What does spread do?
Spread expands or shrinks the shadow size. Negative spread makes the shadow tighter; positive spread makes it larger.
Is inset shadow supported?
Yes. Toggle inset on any layer to create an inner shadow.
Can I use these values in Tailwind?
Yes. You can place the generated value into custom utilities or CSS variables used by Tailwind.
