Glass Card
This is how your glassmorphism effect looks with real content.
background: rgba(255, 255, 255, 0.2);
backdrop-filter: blur(10px) saturate(100%);
-webkit-backdrop-filter: blur(10px) saturate(100%);
border-radius: 16px;
border: 1px solid rgba(255, 255, 255, 0.5);How to Create a Glassmorphism Effect
- 1
Choose a Background
Select a vibrant gradient or colorful image as the page background. Glassmorphism relies on content behind the glass being visible, so rich colors and gradients produce the best results. Use the background color pickers to set your gradient. - 2
Adjust Blur and Transparency
Use the blur slider to control the frosted glass intensity. Higher blur values create a stronger frosting effect. Then set the transparency slider to determine how much background shows through. A value between 0.15 and 0.35 usually works well. - 3
Refine Borders and Radius
Add a subtle semi-transparent border to define the glass edge. Increase the border radius for softer, rounded corners that complement the glass aesthetic. Most glassmorphism designs use a radius between 12px and 24px. - 4
Copy and Use the CSS
Once you are satisfied with the preview, click Copy CSS to grab the generated code. Paste it into your stylesheet and apply the class to any card, modal, or sidebar element. The output includes the -webkit-backdrop-filter prefix for Safari compatibility.

What is Glassmorphism?
Glassmorphism is one of the most popular UI design trends in modern web development. Inspired by the frosted glass panels in Apple's macOS and Microsoft's Fluent Design, the technique uses CSS backdrop-filter to blur the content behind an element while keeping it partially visible. This generator lets you fine-tune blur intensity, background transparency, saturation, border radius, and border width in real time, then copy the production-ready CSS with a single click.
The effect works best when paired with vibrant gradients or image-heavy layouts. You can build matching backgrounds using the Gradient Generator, extract dominant colors from photos with the Image Color Extractor, and ensure your glass cards maintain readable contrast by running a quick check with the Contrast Checker. Together, these tools give you a complete design workflow without leaving the browser.
Because the generated CSS runs entirely on the client side, no data is uploaded to any server. You can iterate freely, export the code, and drop it into any framework such as React, Vue, Tailwind CSS, or plain HTML. For additional polish, try combining the glass card with a layered Box Shadow to add depth, or pair it with a custom Color Palette for a cohesive color scheme across your project.
How It Compares
Glassmorphism sits alongside several other popular CSS design trends. Neumorphism uses soft inset and outset shadows to create an extruded, clay-like look, but it often struggles with accessibility because the low-contrast shadows make interactive elements hard to distinguish. Glassmorphism, by contrast, naturally layers elements with transparent depth, making it easier to maintain visual hierarchy and meet WCAG contrast requirements when paired with the right text color.
Compared to flat design, glassmorphism adds a sense of physical depth without the heavy skeuomorphic textures of earlier eras. The trade-off is browser support: backdrop-filter requires Chrome 76+, Safari 9+, Edge 79+, or Firefox 103+. For projects that must support older browsers, a semi-transparent background color fallback is recommended. Despite this caveat, glassmorphism remains the top choice for landing pages, dashboards, and mobile interfaces where visual appeal and modern aesthetics are a priority.
