The frosted glass aesthetic
Glassmorphism brings a tactile, layered quality to UI by simulating translucent materials. The core technique pairs a semi-transparent background with a backdrop-filter blur, which blurs everything behind the element to create the illusion of frosted or etched glass. A subtle border with low opacity and a soft shadow completes the effect.
The generator places your glass panel over a colourful gradient background so you can see the blur in action. Adjust the blur radius, background opacity, border opacity, and shadow to dial in exactly the right level of translucency.
Practical considerations
Glassmorphism works best as an overlay design — modals, cards, navbars, and side panels. Keep background opacity above 0.15 to maintain readable text, and ensure text overlays have sufficient contrast against the blurred background behind them. The backdrop-filter property is widely supported in modern browsers but not in Internet Explorer.
