Glassmorphism CSS Generator

Generate the glassmorphism / frosted-glass CSS effect with backdrop-filter: blur(), semi-transparent background, subtle border, and soft shadow. Live preview on a gradient backdrop so you can actually see how the effect lands.

How to use the Glassmorphism CSS Generator

Adjust the sliders; the preview updates live on a gradient backdrop. Blur is the dominant effect — 8-16px is the sweet spot for most uses. Higher saturation makes the backdrop's colors pop through; lower mutes them. Add a thin light-colored border for a more pronounced glass edge.

Browser support and fallbacks

backdrop-filter works in all modern browsers (Chrome 76+, Safari 9+, Firefox 103+). Where unsupported, the effect degrades gracefully to a plain semi-transparent background — readable, just not blurred. The performance hit of backdrop-filter is small for one or two elements; avoid stacking many on the same page.
