Frequently Asked Questions

Outer vs inset shadow — when do I use each?
Outer (default) makes elements appear elevated above the page. Inset makes them appear pressed in (good for inputs, buttons in their pressed state, recessed panels).
What's the difference between blur and spread?
Blur softens the shadow's edge. Spread expands or contracts the shadow's overall size. Negative spread shrinks it.
Can I stack multiple shadows?
Yes — the 'xl' preset shows the pattern (two layers). For now this UI generates a single layer; copy the output and combine manually for multi-layer effects.
