FAQ
What is the difference between blur and spread?
Blur controls how soft/diffused the shadow edges are. Spread controls how much the shadow expands or contracts from the element's size. Positive spread makes it larger, negative makes it smaller.
Can I add multiple shadows?
Yes. Click 'Add Layer' to stack up to 5 shadow layers. Each layer has independent controls for all parameters.
What does inset do?
Inset moves the shadow inside the element instead of outside, creating an inner shadow or pressed-in effect.
Does it work for text-shadow too?
This tool generates box-shadow CSS. Text-shadow uses a similar syntax but without the spread value or inset option. You can adapt the output manually.
Is this tool free?
Yes, completely free with no limits or registration required.
