Frequently Asked Questions
What is glassmorphism?
Glassmorphism is a UI style that mimics frosted glass: a semi-transparent background with a background blur (backdrop-filter), a subtle border, and a soft shadow, so content behind it shows through blurred.
What is neumorphism?
Neumorphism ('new skeuomorphism') is a soft-UI style where elements look extruded from the background using two shadows — a dark one and a light one on opposite corners — over a single flat background colour.
Does backdrop-filter work in all browsers?
Modern browsers support it, but include the -webkit-backdrop-filter prefix (this tool adds it) for Safari. Glassmorphism needs a colourful or image background behind the element to be visible.
Is the CSS free to use?
Yes. The CSS this tool generates is yours to use in any project, personal or commercial, with no attribution required.
