CSS Glassmorphism Generator
Design a frosted-glass card by tuning blur, transparency, and border — with a live preview and copy-ready CSS including the Safari fallback.
Build the frosted-glass look, precisely
Glassmorphism gives cards, navbars, and modals a light, layered feel — content behind them shows through a soft blur, tinted by a translucent panel. Getting it right means balancing four things: the blur radius, how transparent the panel is, its tint color, and the corner radius. This generator exposes all four as sliders with a live preview over a colorful backdrop, so you can see the effect exactly as users will.
The output includes the semi-transparent background, both backdrop-filter and the
-webkit- prefix for Safari, a subtle border, and a soft shadow — the full recipe, ready to paste.
Remember the effect only appears over busy or image backgrounds; over a flat color there's nothing to blur.
Copy-ready CSS
Everything is generated in your browser and updates instantly as you drag the sliders.
Frequently Asked Questions
What is glassmorphism?
Glassmorphism is a UI style that mimics frosted glass: a semi-transparent background, a backdrop blur that softens whatever sits behind it, a subtle border, and a soft shadow.
What CSS property creates the frosted-glass blur?
backdrop-filter: blur() blurs the content behind an element. It needs a semi-transparent background to show through, and a -webkit-backdrop-filter fallback for Safari.
Does glassmorphism work in all browsers?
backdrop-filter is supported in current Chrome, Edge, Firefox, and Safari (with the -webkit- prefix). Always test on a busy background, since the effect is invisible over a flat color.
Is this generator free and private?
Yes. The CSS is generated in your browser — no sign-up and nothing is uploaded.
