How the glassmorphism effect works

A glass panel combines four ingredients: a semi-transparent background so some color from behind shows through, a backdrop-filter: blur() so that background is softened, a thin light border to catch a highlight edge, and a soft shadow to lift the panel off the page. Layer bright, colorful content behind the panel — a gradient, photo or pattern — for the effect to read clearly.

Live gradient backdrops

Pick from sample gradient backdrops to see exactly how the blur and tint interact with color underneath.

Fine-tuned controls

Independently adjust blur strength, tint color and opacity, border and shadow to match your design system.

CSS glassmorphism generator FAQ

What is glassmorphism in CSS?

Glassmorphism is a UI style that mimics frosted glass using a semi-transparent background, a blurred backdrop and a light border to create depth over colorful content.

Which CSS property creates the blur effect?

The backdrop-filter property with a blur() value blurs whatever is behind the element. Safari needs the -webkit-backdrop-filter prefix as well.

Why is my glass effect not showing?

backdrop-filter only blurs content behind the element, so there must be a background image, gradient or other content underneath, and the browser must support the property.

Does glassmorphism work on all browsers?

Support is broad in modern browsers, but very old browsers may ignore backdrop-filter and simply show the solid tint color instead.

Is this glassmorphism generator free to use?

Yes. It runs entirely in your browser with no account, upload or watermark, and the CSS is yours to use anywhere.
