Online CSS glassmorphism effect generator
Glassmorphism simulates frosted translucent glass with semi-transparent backgrounds and blur effects. Popularized by Apple in macOS Big Sur and iOS, it has become one of the most popular UI design trends.
Our generator lets you adjust blur level, background transparency, border thickness, and corner radius. The preview updates in real time over a colorful background.
The generated CSS includes both standard backdrop-filter and -webkit- prefix for Safari. Works in all modern browsers. Ideal for cards, modals, navigation bars, and floating menus.
Frequently asked questions
Is it compatible with all browsers?
The backdrop-filter property is compatible with Chrome, Safari, Edge, and Firefox (since version 103). Safari needs the -webkit- prefix, which our generator includes automatically. Internet Explorer does not support it.
Does glassmorphism affect performance?
The blur effect can consume GPU resources, especially with high values on mobile devices. For better performance, use moderate blur values (4-15px) and apply the effect to few elements simultaneously.
Do I need a special background for it to work?
Yes, glassmorphism needs content behind the element (images, gradients, colors) for the blur effect to be visible. On a solid white background, the effect will be practically invisible.
