About Glassmorphism Generator
OptiPix Glassmorphism Generator creates the popular frosted glass UI effect using CSS backdrop-filter. Adjust blur intensity (0-30px), background opacity (0-100%), background color, border width and color, border radius, and shadow. Preview the glass card overlaid on a background image — choose from 5 built-in presets (gradient, nature, abstract, city, dark) or the default colorful gradient. The preview shows sample content (heading, text, button) inside the glass card for real-world context. Copy the full CSS including vendor prefixes (-webkit-backdrop-filter) and the HTML + CSS snippet. Browser support note included. Everything runs locally in your browser.
How It Works
The tool constructs CSS properties from the slider values: backdrop-filter for blur, rgba() background for transparency, border-radius, border with opacity, and optional box-shadow. The preview applies these styles to a card element overlaid on a background image.
