Frequently Asked Questions

What is the spread radius?+
Spread radius expands or contracts the shadow. Positive values make the shadow larger than the element, negative values make it smaller. A spread of 0 makes the shadow the same size as the element.
Can I add multiple shadows?+
Yes! CSS supports comma-separated multiple box shadows. Layering a tight, dark shadow with a wide, soft one creates realistic, material-design-style depth effects.
