Create stunning frosted glass UI elements with interactive backdrop-filter blur, background opacity, border highlights, and instant cross-browser CSS code generation.
Frosted Glass UI Effect
The heart of glassmorphism is `backdrop-filter: blur()`, which frost-blurs whatever HTML elements sit beneath the card.
A semi-transparent background fill (`rgba(255, 255, 255, 0.25)`) creates the physical glass pane surface.
A delicate 1px semi-transparent white border simulates light bouncing off the chamfered glass edge.
1px solid rgba(255,255,255,0.2)) mimics the refractive bevel of real physical glass, giving the element a crisp edge that separates it from busy background content.
backdrop-filter is fully supported by all modern evergreen browsers (Chrome, Edge, Safari, Firefox, Opera) across desktop and mobile operating systems since 2020.
