Frequently Asked Questions
What is the difference between blur radius and spread radius? ▼
Blur radius creates a soft gradient fade away from the element boundary. Spread radius physically expands (positive value) or shrinks (negative value) the size of the shadow footprint before blur is applied.
How do modern design systems like Tailwind create natural shadows? ▼
Natural shadows typically combine subtle vertical offsets with larger blur radii and low opacity (8% to 15%), mimicking soft ambient daylight rather than harsh dark silhouettes.
Does this generator support inset inner shadows? ▼
Yes! Toggle the "Inset Shadow" switch to project the shadow inside the element borders.
