Frequently Asked Questions
What is the difference between blur and spread in CSS box-shadow?
Blur softens the edges of the shadow, while spread expands or contracts the shadow footprint before blurring.
How do I create an inner shadow?
Check the 'Inset Shadow' option, which places the shadow inside the container frame instead of behind it.
