Glassmorphism works by combining a translucent fill with backdrop-filter, a light border and restrained depth. The preview puts the panel above colorful shapes because blur is only visible when something sits behind the element. Settings and CSS generation run locally in your browser.

What is a glassmorphism generator?
A glassmorphism generator creates the CSS for a translucent, frosted panel while showing the effect on a real background. Adjust tint, transparency, background blur, saturation, border, corners and shadow, then copy a complete class with both standard and WebKit backdrop-filter declarations.

How to use
- 01Choose a starting style
Pick Balanced, Subtle, Frosted or Tinted to load a practical set of glass values.
- 02Tune the glass
Adjust the tint, transparency, backdrop blur, saturation, border opacity, corner radius and shadow while the preview updates live.
- 03Check the background
Make sure shapes behind the panel remain visible enough to reveal the blur without reducing text clarity.
- 04Copy the CSS
Copy the generated .glass-panel class and apply it to an element placed above a visible background.

Who it's for
- Front-end developers can generate a reusable glass panel class for menus, cards, sidebars and modal surfaces.
- UI designers can compare subtle, frosted and tinted treatments before handing exact CSS to a developer.
- Design-system teams can establish consistent blur, opacity, radius and shadow values for translucent surfaces.
- Students learning CSS can see how backdrop blur differs from blurring the panel's own content.
FAQ
Is my glassmorphism design uploaded anywhere?
No. Every slider, preview update and CSS value is calculated in your browser. The generator does not upload your colors, settings or copied code to a processing service.
Is this glassmorphism generator free?
Yes. You can use every preset and control, preview the result and copy the generated CSS without an account, payment or usage limit.
What browsers support glassmorphism CSS?
Modern browsers support backdrop-filter, but older browser versions may not render it. The generated class includes both backdrop-filter and -webkit-backdrop-filter. Keep the translucent background color as a readable fallback when blur is unavailable.
Why is the glass blur not visible?
Backdrop blur needs visible detail behind the glass element. If the parent background is a flat color, there is nothing obvious to blur. Put an image, gradient or decorative shape behind the panel and confirm the panel's fill is partly transparent.
What is the difference between blur and transparency?
Transparency controls how much of the background shows through the panel color. Backdrop blur softens the background detail seen through it. A balanced glass surface usually needs both, plus a subtle border to define its edge.
Does backdrop-filter blur text inside the card?
No. backdrop-filter processes the content behind an element. Text and controls inside the glass panel stay sharp. The ordinary filter property behaves differently and can blur the element and its children.
How do I keep glassmorphism accessible?
Use enough panel opacity and text contrast, especially over busy images. Avoid relying on transparency alone to separate controls. Test each real background and provide a solid-enough fallback color for browsers or users where backdrop filtering is unavailable.
