What this glassmorphism generator does
Glassmorphism is the frosted-glass look built from a semi-transparent tinted background stacked over a backdrop-filter: blur(), usually finished with rounded corners and a faint light border. Drag the sliders to set the blur radius in pixels, the background transparency, the corner radius, and pick a tint color, while a live preview panel sits over a colorful gradient so you can see the frosting in real time. The tool then prints a ready-to-paste CSS block you can copy with one click.
Copy-ready, cross-browser output
The generated code writes the tint as an rgba() background using your color and transparency, a backdrop-filter: blur(Npx), and a matching -webkit-backdrop-filter so the effect also works in Safari and older WebKit browsers. Corner radius is emitted as border-radius, and an optional 1px light border adds the subtle glass edge. Paste the block straight into a class in your stylesheet or an inline style attribute.
Frequently asked questions
Why does the output include a -webkit-backdrop-filter line?
Safari and some older WebKit-based browsers only recognize the prefixed -webkit-backdrop-filter property. The generator emits both the standard and prefixed versions so the blur renders consistently across browsers.
Why is my glass effect invisible on a plain background?
backdrop-filter blurs whatever sits behind the element, so the frosting only shows when there is content — an image, gradient, or overlapping elements — behind the glass panel. Over a flat solid color there is nothing to blur.
Is anything I create uploaded to a server?
No. The preview and the CSS are generated entirely in your browser with JavaScript. Nothing you enter is sent, stored, or uploaded anywhere.
