What CSS properties power glassmorphism?

Glassmorphism relies on backdrop-filter: blur() for the frosted effect, a semi-transparent background-color with rgba(), a subtle border with rgba white, and box-shadow for depth. These four together create the characteristic glass look.

Is backdrop-filter widely supported?

backdrop-filter is supported in all modern browsers (Chrome, Edge, Safari, Firefox 103+). For older Firefox versions you may need the -webkit- prefix, which the generated CSS includes automatically.

How do I use the copied CSS?

Apply the copied CSS to any element that sits on top of a colorful or image background. The element itself needs position: relative or higher; the parent context supplies the background that blur is applied against.

Why does the effect look flat on a white background?

backdrop-filter blurs whatever is behind the element. On a plain white background there is nothing to blur, so the effect looks invisible. Always place the glass element over an image or gradient for the full frosted-glass result.

Can I use this in Tailwind CSS?

Yes. Tailwind includes backdrop-blur-* utilities and bg-white/10 for transparency. The generated CSS values map directly to Tailwind arbitrary values if you prefer the utility-class approach.
