Frequently Asked Questions

Subtle vs dramatic shadows?

Subtle: 0 2px 8px rgba(0,0,0,.1); dramatic: 0 20px 60px rgba(0,0,0,.3). Layer two shadows (tight + diffuse) for premium depth.

Inset shadows?

Pressed and inner-glow effects via inset keyword — form fields and toggles gain tactile feel. Pair with outer shadow sparingly.

Performance?

Large blurred shadows cost paint time — animate transform/opacity instead of box-shadow for 60fps motion.

Do shadow styles upload?

No — generation runs locally in your browser. Nothing leaves your device.
