Glassmorphism Generator

Glassmorphism is a UI design style that mimics frosted glass. It uses a translucent background with backdrop-filter: blur() to blur the content behind an element. It’s popular in macOS, Windows 11, iOS, and modern web interfaces for cards, navigation, and modal windows.

Key properties: background with rgba/hsla (semi-transparent color), backdrop-filter: blur() to blur the background, a semi-transparent border for a light refraction effect, and border-radius for rounded corners. Add box-shadow for depth.

Increase the blur amount (12–20px) and/or background opacity. Use dark text on light glass or white text on dark glass. Check contrast with Color Contrast Checker. Add a subtle text shadow to improve readability.

backdrop-filter is supported in Chrome, Edge, Safari, and Firefox 103+. Safari requires the -webkit-backdrop-filter prefix. For older browsers, provide a fallback — an opaque background using @supports not (backdrop-filter: blur(1px)).

backdrop-filter with blur triggers a repaint of the compositing layer. Large blurred areas can reduce FPS on mobile devices. Limit the size of glass elements, avoid animating blur, and test on low-end devices.
