About this tool

The frosted-glass look in one line

Glassmorphism is the translucent, blurred "frosted glass" card you see in modern UIs — a semi-transparent background plus backdrop-filter: blur(), usually with a subtle border and shadow. Tune the blur, transparency, tint and corners and copy the CSS.

Tips for it to actually work

  • Put it over something colorful — the blur needs a busy or gradient background behind it to read as glass.
  • Keep transparency moderate (~0.1–0.2) so the blur shows through.
  • Include the -webkit- prefix for Safari.

Frequently asked questions

Common questions about the Glassmorphism Generator.

What is glassmorphism?

A UI style that uses a translucent, blurred background to mimic frosted glass, usually with a thin border and soft shadow.

Why isn’t my glass effect showing?

backdrop-filter needs content behind it — place the card over a colorful or gradient background, and keep the background semi-transparent.

Does backdrop-filter work in all browsers?

Modern browsers support it; add the -webkit-backdrop-filter prefix for Safari.

How transparent should the background be?

Around 0.1–0.2 opacity so the blur reads as glass rather than a solid panel.
