How to Create This

It's all about layers and blur.

1. Background Blur: backdrop-filter: blur(20px)
2. Transparency: background: rgba(255, 255, 255, 0.1)
3. Border: A thin, semi-transparent border to define the edge.
4. Shadow: A soft drop shadow to lift it up.

Combine these to create a surface that feels like frosted glass.
