What is "spread" in a CSS box-shadow?

Spread expands or contracts the shadow in all directions. A positive spread makes it larger than the element; a negative spread makes it smaller.

Can I create an inner shadow with this tool?

Yes — toggle the "inset" option on a shadow layer to make it an inner (inset) shadow that appears inside the element's border rather than outside.
