Glassmorphism is a UI design trend characterized by a frosted-glass effect on elements. This technique creates a visual hierarchy by making elements translucent, allowing the background to peek through with a blur. The key ingredients, which our Glassmorphism Generator helps you control, are transparency, background blur, and a subtle border to mimic the edge of a piece of glass.
Popularized by major tech companies like Apple (in macOS Big Sur) and Microsoft (with their Fluent Design System), glassmorphism adds depth and a modern, airy feel to interfaces. It creates a sense of space and layering, making the user interface feel more dynamic and less flat. Our generator simplifies the creation of this frosted glass UI, producing cross-browser compatible CSS that you can directly use in your projects without writing code from scratch.

Enhanced Focus
Guide user attention with frosted elements that subtly highlight important content while maintaining background context.
The 4 Core Principles of Effective Glassmorphism
Creating a convincing glass effect is more than just applying a CSS filter. It’s a balance of four key elements, all of which you can control with our glassmorphism generator. Understanding these principles will help you create more effective and beautiful designs.
- The Background: The magic of glassmorphism is seeing what’s behind the glass. Therefore, a vibrant, colorful, or textured background is crucial. A plain, solid-color background won’t show off the blur effect. Think of it like looking through a real piece of frosted glass—the more interesting the scene behind it, the more beautiful the effect.
- Transparency: This is the “glass” in glassmorphism. The transparency level determines how much of the background is visible. Low transparency makes the element look solid, while high transparency can make it hard to read the content on top. Our generator’s “Transparency” slider helps you find the perfect sweet spot for your design.
- Blur: The `backdrop-filter: blur()` property is the engine of this effect. It creates the “frosted” look by blurring the background behind the element. A higher blur value creates a more opaque, frosted appearance, which can improve readability. A lower value creates a clearer, more subtle effect.
- The Border: A subtle, semi-transparent border is the finishing touch. It defines the edges of the glass pane, making it “lift” off the background and giving it a more realistic, physical quality. Our tool lets you control the size and color of this border to perfectly match your aesthetic.
How to Use This Glassmorphism Generator
Our tool is designed for speed and simplicity. Follow these four steps to generate your perfect CSS glass effect in seconds:
- Adjust Controls: Use the intuitive sliders and color pickers to design your ideal glass effect. Tweak the blur, transparency, border, and radius to match your vision.
- Live Preview: See your changes in real-time in the preview window. This instant feedback loop allows for rapid experimentation without any guesswork.
- Copy CSS: Once you’re happy with the result, click the “Copy CSS” button. The clean, cross-browser compatible code is instantly copied to your clipboard.
- Implement: Paste the generated CSS into your project’s stylesheet and apply the `.glass-element` class (or a name of your choice) to any HTML element you want.

Glassmorphism is incredibly versatile. Here are some inspiring ideas to get you started:
UI Trends: Glassmorphism vs. Neumorphism vs. Flat Design
Understanding how glassmorphism fits into the broader landscape of UI design can help you make informed decisions for your projects. Here’s a quick comparison with other popular trends:
Glassmorphism
Core Idea: Layered depth and transparency. Elements feel like they are floating panes of frosted glass on top of a background. It’s defined by the `backdrop-filter` property.
Best For: Dashboards, app overlays, and interfaces where a sense of context and modern elegance is desired.
Neumorphism
Core Idea: Soft, extruded plastic. Elements are the same color as the background and are only defined by soft inner and outer shadows, making them look attached to the surface.
Best For: Minimalist interfaces, smart home controls, and projects where a subtle, tactile feel is important.
Flat Design / Flat 2.0
Core Idea: Simplicity and usability. Focuses on two-dimensional elements, bright colors, and clean typography. Flat 2.0 adds subtle shadows or gradients for a bit of depth.
Best For: Content-heavy websites, mobile apps, and designs where clarity and speed are the top priorities.
Our Glassmorphism CSS Generator focuses on delivering the best tool for the glass effect, but understanding these other styles helps you appreciate the unique, layered aesthetic that only glassmorphism can provide.
Frequently Asked Questions
Glassmorphism is a UI design technique that creates a translucent, frosted-glass effect. It uses background blur, transparency, and subtle borders to make elements appear as if they’re made of glass, allowing background content to show through while maintaining readability.
Glassmorphism relies on the `backdrop-filter` CSS property, which is supported by all modern browsers including Chrome, Edge, Firefox, and Safari. Our glassmorphism generator includes the `-webkit-` prefix for older Safari versions for better compatibility. For unsupported browsers, the effect will gracefully degrade to a simple transparent background.
When implemented thoughtfully, yes. Key considerations are to maintain sufficient color contrast between text and the glass background (WCAG AA standard), not making the background too busy, and using a blur level that doesn’t strain the eyes. Always test your designs against accessibility guidelines.
The `backdrop-filter` property can be computationally intensive for browsers, as it requires rendering what’s behind the element. It’s best to use it sparingly on smaller elements (like cards or modals) rather than large, frequently changing sections of your page to ensure a smooth user experience, especially on older devices.
Absolutely! Glassmorphism works beautifully in dark mode. In our generator, simply adjust the “Glass Color” to a dark shade (like black) and set your desired transparency. Using a light-colored border can help the element pop against a dark website background, creating a very sleek and modern feel.
This is a critical distinction. Using `opacity` makes the entire element—including its content (text, icons)—transparent. This is bad for readability. Our tool uses `rgba()` or `hsla()` for the `background` color, which only makes the background transparent, leaving the content fully opaque and legible. This is the correct way to achieve the glass effect.
A great way is to use CSS’s `@supports` rule. You can define a simple semi-transparent background color first, and then override it with the `backdrop-filter` for browsers that support it. Example:
.glass-element { background: rgba(255, 255, 255, 0.5); }
@supports (backdrop-filter: blur(10px)) { .glass-element { background: rgba(255, 255, 255, 0.1); backdrop-filter: blur(10px); } }
There are three main techniques: 1) Increase the blur radius to make the background less distracting. 2) Decrease the transparency to make the glass more opaque. 3) Add a subtle `text-shadow` to the text (e.g., `text-shadow: 0 1px 2px rgba(0,0,0,0.2);`) to help it stand out from the background.
You can achieve this by placing multiple glass elements on top of each other using CSS positioning (e.g., `position: absolute` and `z-index`). To create a sense of depth, use slightly different values from our glassmorphism generator for each layer. For example, the element on top could have a slightly lower blur and transparency than the one below it.
The glassmorphism effect relies on blurring the content *behind* the element. If the background is a single solid color, there’s nothing interesting to blur, and the effect will be invisible (appearing only as a semi-transparent color). A varied, colorful, or textured background is essential to see the frosted glass effect clearly and appreciate its beauty.
