Frequently Asked Questions
What is a CSS box-shadow?
A CSS box-shadow adds a shadow effect around an element's frame using the box-shadow property, defined by a horizontal offset, vertical offset, blur radius, spread radius, and color, without needing an image.
Can I stack multiple shadows on one element?
Yes. The box-shadow property accepts a comma-separated list of shadows. This generator lets you add multiple layers, each with its own offset, blur, spread, color, and opacity, to build depth effects like layered or neumorphic shadows.
What is the difference between inset and outer shadows?
An outer shadow (the default) is cast outward from the element's edges, as if the element is raised. An inset shadow is drawn inside the element's border, as if the element is pressed inward. Toggle the Inset switch on any layer to flip it.
How do offset, blur, and spread work?
Offset X and Y move the shadow horizontally and vertically. Blur radius softens the shadow's edge; a higher value spreads the shadow further and fades it more. Spread radius grows or shrinks the shadow's size in every direction before blurring is applied.
Can I copy the generated CSS?
Yes. Click Copy CSS to copy the complete box-shadow declaration, including every layer, to your clipboard, ready to paste into your stylesheet.
