Frequently Asked Questions

How do I create a CSS box-shadow?

Set X and Y offset, blur, spread, color, and opacity. The tool shows a preview and builds the CSS rule.

What do offset X and offset Y do?

Offset X moves the shadow horizontally, and offset Y moves it vertically. Positive values move the shadow right and down; negative values move it left and up.

What is blur in box-shadow?

Blur controls how soft the shadow looks. A larger value makes the shadow softer and wider.

What is spread?

Spread expands or shrinks the shadow area. A positive value makes the shadow larger; a negative value makes it smaller.

What does inset mean?

Inset makes the shadow inner: it appears inside the element instead of outside.

Can I use multiple shadows?
