Glassmorphism CSS Generator
Design a frosted-glass card and copy the backdrop-filter CSS.
About Glassmorphism CSS Generator
Glassmorphism CSS Generator designs the frosted-glass surface that has become a staple of modern UI — semi-transparent panels over a blurred background. You tune blur radius, surface opacity, saturation, tint color, and corner radius; a subtle border and shadow are applied to the output by default so the panel reads as a discrete element. The CSS — including the -webkit- prefix for older Safari — is composed for you over a sample backdrop so you can see the effect in context.
Worked example: with the defaults, the generator outputs background: rgba(255, 255, 255, 0.20); backdrop-filter: blur(16px) saturate(140%); border: 1px solid rgba(255, 255, 255, 0.3); border-radius: 16px; and a subtle drop shadow. Tweak the sliders and pick a tint color to find the right look by eye, then copy the CSS in one click. Because the effect only works visually when the element sits over something colorful — a photo, a gradient, or another colored surface — a fixed sample backdrop is part of the preview.
Two practical caveats worth knowing. backdrop-filter is well-supported across modern browsers now (Safari needed the -webkit- prefix originally, Firefox added support relatively recently), but very old browsers will simply ignore it and show the underlying semi-transparent background — typically still acceptable. Performance: rendering a blurred copy of whatever sits behind the element is not free, especially at large blur radii on large surfaces, so prefer glass on accent panels rather than as a full-page background on a busy interface. And accessibility: contrast between text and the blurred backdrop is harder to predict, so check any text you place on top with the WCAG Contrast Checker.
Generation runs entirely in your browser.
