Why isn't the blur effect working on my website?

For 'backdrop-filter: blur()' to work, the element's background color must be semi-transparent (e.g., using RGBA). If the background is solid (opacity 1), you won't be able to see the blurred elements behind it.

Is Glassmorphism bad for accessibility (a11y)?

It can be if misused. Ensure that any text placed on top of a glassmorphic element has a high enough contrast ratio against the background. Don't rely solely on the blur to create contrast, as background colors can shift.

Does this generate Tailwind CSS classes?

Yes! In addition to standard Vanilla CSS, our tool generates a string of Tailwind CSS utility classes using arbitrary values so you get the exact pixel-perfect design in your Tailwind project.

The Ultimate CSS Glassmorphism Generator

Glassmorphism is one of the most popular UI design trends of the decade. Characterized by frosted-glass effects, vivid background colors shining through semi-transparent panels, and subtle light borders, it adds depth, hierarchy, and a premium "macOS" feel to any web application.

However, writing the CSS for Glassmorphism from scratch is tedious. Getting the exact balance of backdrop-filter, rgba() transparency, and box-shadow takes constant tweaking. Our CSS Glassmorphism Generator provides a live, interactive environment to build the perfect frosted glass component in seconds.

The Anatomy of a Glassmorphism Component

To achieve the perfect glass effect, several CSS properties must work in harmony:

Background Transparency (rgba): The background color must have an alpha channel (opacity) below 1.0. Usually, a white background with 10% to 40% opacity works best for light mode, while a dark background works for dark mode.
Backdrop Filter (backdrop-filter: blur()): This is the magic property. It blurs whatever is behind the element, creating the frosted glass illusion. (Note: Always include the -webkit-backdrop-filter prefix for Safari compatibility).
Subtle Borders: A 1px solid border with a very low opacity white (e.g., rgba(255, 255, 255, 0.1)) mimics the edge of a physical pane of glass catching the light.
Drop Shadows: A soft, wide box-shadow lifts the element off the background, enhancing the feeling of floating depth.

Vanilla CSS vs. Tailwind CSS

Our generator supports both modern workflows:

Vanilla CSS: We provide the raw CSS properties ready to be pasted into your .css stylesheet or styled-components.
Tailwind CSS: If you use Tailwind, trying to memorize the arbitrary value syntax for exact blur radii and RGBA colors is annoying. We automatically generate the exact utility classes (e.g., backdrop-blur-[10px], bg-[rgba(...)]) so you can paste them directly into your React/Next.js components.

Browser Compatibility

The backdrop-filter property is now widely supported across all modern browsers (Chrome, Edge, Firefox, Safari). However, it is always a good practice to provide a solid background color fallback for older browsers or users who have disabled transparency effects in their OS accessibility settings.
