Free Online CSS Glassmorphism & Box Shadow Generator
Modern frontend user interfaces frequently employ Glassmorphism—a design aesthetic that mimics the visual look of frosted, translucent glass hovering above vibrant backgrounds. Popularized by Apple macOS Big Sur, Windows Fluent Design, and modern SaaS dashboards, glass cards give web interfaces unprecedented visual depth, futuristic polish, and organic elevation.
The TechTools Free CSS Glassmorphism Generator gives UI designers and web developers complete real-time interactive control over backdrop blur radius, background tint opacity, border edge highlights, and layered box shadows. Test your components across dynamic mesh and neon gradients, then export clean, production-ready Vanilla CSS or Tailwind CSS utility classes with a single click.
How to Create Glassmorphism UI in 4 Steps
- Fine-Tune Backdrop Blur: Adjust the Backdrop Blur slider between 8px and 25px to achieve the perfect frosted diffusion without obscuring background shapes.
- Balance Opacity & Tint: Set card opacity between 10% and 25% for true translucency, and pick a custom tint color that harmonizes with your web application's palette.
- Add Crisp Border Highlights: A subtle 1px semi-transparent white border (15% to 30% opacity) simulates the natural specular reflection on the edge of physical glass.
- Export Vanilla or Tailwind CSS: Toggle between pure CSS rules or Tailwind CSS utility classes and paste the code directly into your stylesheet.
