Glassmorphism CSS Generator | Frosted Card Styles
Create frosted-glass CSS cards with backdrop blur, transparency, border, shadow, and copy-ready style output.
Create Frosted-Glass CSS Cards
Adjust background color, transparency, blur, outline, and shadow to generate glassmorphism CSS for cards, panels, modals, profile blocks, and landing page sections.
Check Browser and Contrast Support
Glass effects depend on backdrop-filter support and the background behind the element. Test readability on mobile and avoid placing low-contrast text over busy images.
About This Tool
Glassmorphism Generator produces CSS code for the frosted-glass UI effect that blurs the background behind a floating card or panel. It uses backdrop-filter, transparency, and border styling to create a layered glass aesthetic.
When to Use It
Use this when designing a UI card or modal that sits over a colourful or blurred background, when implementing the glassmorphism style in a web project, or when matching a design from a Figma mockup.
How to Use
- Adjust the blur, transparency, and saturation sliders.
- Set the border opacity and border radius.
- Preview the result against a sample gradient background.
- Copy the generated CSS.
Frequently Asked Questions
Does glassmorphism work in all browsers?
backdrop-filter is supported in Chrome, Edge, and Safari. Firefox support is limited. Add a solid fallback background for browsers that do not support it.
Does it affect performance?
backdrop-filter is GPU-accelerated on modern hardware but can strain low-powered devices if applied to many elements. Use it for key UI components only.
What background works best behind a glass effect?
Glassmorphism looks best over a colourful, blurred, or gradient background. It loses impact over plain white or very dark backgrounds.
