FAQ

What does the spread value do?

Spread grows (positive) or shrinks (negative) the shadow before the blur is applied. A small negative spread with a large blur creates a soft, modern shadow.

What is an inset shadow?

Inset draws the shadow inside the element instead of outside — useful for pressed buttons, inputs, and inner depth.
