Frequently Asked Questions (FAQ)
What is the difference between blur radius and spread radius?
Blur radius controls how soft and feathered the shadow edge appears. Spread radius expands or contracts the overall dimensions of the shadow before blur is applied, allowing shadows smaller or larger than the element itself.
Is Glassmorphism supported on all major web browsers?
Yes! backdrop-filter is supported in all modern versions of Chrome, Safari, Edge, and Firefox. The generator also includes -webkit-backdrop-filter for seamless iOS Safari rendering.
Is this tool free to use for commercial web projects?
Yes. NexTools is 100% free with no copyright restrictions or license fees. You are free to use any generated CSS code in commercial and personal websites.
