Online Glassmorphism CSS Generator
Create beautiful Frosted Glass effects for your UI instantly. Adjust blur, transparency, and saturation to generate production-ready CSS or Tailwind classes.
Glassmorphism is a design trend popularized by Apple's macOS Big Sur and Microsoft's Windows 11. It uses a combination of background blur and translucency to create a sense of depth and hierarchy.
The Secret Sauce
The key property is backdrop-filter: blur(). Unlike regular opacity which fades the whole element, this property only blurs what is behind the element, simulating real frosted glass.
Layering Strategy
Glassmorphism works best on colorful, busy backgrounds. If you place a glass card on a solid white background, the effect disappears. Always ensure there is visual noise behind your glass layer.
Tailwind Support
We generate JIT (Just-In-Time) arbitrary values for Tailwind CSS. Simply copy the classes like backdrop-blur-[10px] and paste them directly into your HTML or React components.
CSS Implementation
1. Background Color
You must use RGBA with a low alpha value (e.g. 0.2). If the alpha is 1 (solid), you won't see through it. If it's 0 (invisible), the glass won't have a tint.
2. The Border
A subtle, semi-transparent white border (1px solid rgba(255,255,255,0.3)) is crucial. It mimics the glossy edge of physical glass catching the light.
3. Browser Support
Modern browsers support backdrop-filter well. However, older Safari versions require the -webkit- prefix. Our generator includes this automatically for maximum compatibility.
FAQ
Why isn't the blur working?
Check if your background color is too opaque. If background: rgba(255,255,255, 1), it's solid paint. Lower the last number (alpha) to 0.2 or 0.3.
Is this bad for performance?
backdrop-filter can be GPU intensive if used on very large areas or too many elements at once. Use it sparingly for cards, modals, or navigation bars.
