Create the frosted-glass effect
Glassmorphism is the frosted-glass look, a translucent panel that softly blurs whatever content sits behind it, and it has become a signature of modern interface design. This generator builds the necessary CSS with a live preview, letting you adjust the blur amount, the opacity and the colour until it looks right, then copy the finished result straight into your project. The live preview matters because the effect is all about balance, and balance is something you judge by eye.
How the effect is built
The effect combines a semi-transparent background colour with a backdrop blur that frosts the content showing through the panel from behind, plus a subtle light border and a soft shadow to give the pane of glass a believable edge. The balance between these is delicate: make the panel too transparent and any text placed on it becomes unreadable, make it too opaque and the whole glass illusion simply disappears. Adjusting with a live preview is how you find the precise point where it convincingly reads as glass while staying legible.
Copy the CSS
It runs entirely in your browser, so nothing you enter is uploaded and the generated code is yours to paste straight into a project. Because it works client-side, you can iterate freely, regenerating as often as you like without a round trip to any server.

Frequently Asked Questions
What is glassmorphism?
The frosted-glass look: a translucent panel that blurs whatever sits behind it, giving a sense of depth and layering in an interface.
How is the effect made?
With a semi-transparent background and a backdrop blur that frosts the content behind, plus a subtle border and shadow to define the glass edge.
What is the main pitfall?
Legibility. Too transparent and text on the panel becomes hard to read; too opaque and the glass effect vanishes. The live preview helps you find the balance.
Does backdrop blur work everywhere?
It is widely supported in current browsers. A solid fallback background is wise for older ones so the panel stays readable.
Is my input uploaded?
No. The generator runs entirely in your browser.
