Frequently asked questions

How do I add multiple shadows?

In CSS you can specify multiple shadows separated by commas: box-shadow: 0 2px 4px rgba(0,0,0,0.1), 0 8px 24px rgba(0,0,0,0.06). The generator lets you add up to 4 shadows and combine them in any order.

What is an inset shadow?

The inset keyword makes the shadow inner — it appears inside the element rather than outside. Useful for a pressed/recessed effect or inner glow.

How does box-shadow affect performance?

box-shadow is one of the most expensive CSS effects. A large blur radius on many elements can reduce FPS. For animated elements, consider using filter: drop-shadow() instead — it is hardware-accelerated.
