Why does my glass card look wrong on some backgrounds?

Backdrop blur needs content behind the element to blur. Make sure the card sits over an image, gradient, or patterned background — over a flat color the effect is nearly invisible.

How do I keep the text readable on glass cards?

Increase the background opacity slightly and use high-contrast text. The generator lets you tune transparency until the text passes contrast requirements.

About this tool

The Glassmorphism Generator creates the frosted-glass card effect — a translucent background with backdrop blur, subtle border, and soft shadow. Adjust blur, transparency, saturation, and border radius, then copy production-ready CSS.

The output includes both the standard backdrop-filter and the -webkit- prefixed version for Safari compatibility. Preview your settings on light and dark backgrounds before copying.

How to use

1Drag the Blur Radius and Alpha Opacity sliders.
2Pick a surface tint with the color picker.
3Preview the frosted-glass effect live on the sample surface.
4Copy the generated CSS ruleset.

Frequently asked questions

It's supported in all modern browsers. Safari requires the -webkit-backdrop-filter prefix, which this tool includes automatically in the generated CSS.
