backdrop-filter for Frosted Glass

Create frosted glass blur effects on elements overlaid on other content using backdrop-filter.

What is backdrop-filter?

backdrop-filter applies graphical effects to the area behind an element rather than to the element itself. The element must have some transparency (background with alpha < 1 or no background) to reveal the filtered backdrop.

Frosted Glass Effect

The classic frosted glass pattern:

.glass-card {
  background: rgba(255, 255, 255, 0.15);
  backdrop-filter: blur(12px) saturate(180%);
  -webkit-backdrop-filter: blur(12px) saturate(180%);
  border: 1px solid rgba(255,255,255,0.3);
  border-radius: 12px;
}
