Frequently Asked Questions

What does the blur radius control?

The blur radius controls how soft or sharp the shadow edge appears. A value of 0 produces a hard-edged shadow, while larger values create a softer, more diffused effect.

What is an inset shadow?

An inset shadow appears inside the element rather than outside, creating a pressed-in or embossed look. Toggle the Inset checkbox to switch between outer and inner shadow modes.

Can I stack multiple shadow layers?

Yes. CSS supports multiple comma-separated box shadows. Click "Add Layer" to add another shadow and switch between layers using the layer tabs to configure each one independently.
