Glassmorphism only works when there's colour and imagery behind it — the preview is intentionally placed over a colorful gradient.

Glass Preview

backdrop-filter · rgba background

CSS

.glass {
  background: rgba(255, 255, 255, 0.20);
  backdrop-filter: blur(10px) saturate(150%);
  -webkit-backdrop-filter: blur(10px) saturate(150%);
  border: 1px solid rgba(255, 255, 255, 0.30);
  border-radius: 12px;
}

How to use

Click a preset button (e.g. Frosted, Tinted, Dark) to start from a ready-made style.
Adjust background opacity, blur radius, border opacity, and background colour using the controls.
Watch the card preview update live against the gradient background.
Copy the generated CSS (backdrop-filter, background, border) and paste it into your project.

Examples

Setting blur 12px, background rgba(255,255,255,0.15), border rgba(255,255,255,0.3) produces a subtle frosted-glass card effect.
The Dark preset applies a dark semi-transparent background with a muted blur, suitable for dark-themed dashboards.
