Is this CSS Glassmorphism Generator free?

Yes. The tool is free and runs locally in your browser with no signup required.

Can I use the generated CSS on commercial websites?

Yes. You can adapt the generated CSS and HTML for personal or commercial projects. Test and review the code before shipping it to production.

What does backdrop-filter do?

backdrop-filter affects the pixels behind a semi-transparent element, creating blur and saturation effects that produce the frosted-glass look.

Why does the blur effect not show clearly?

Blur is less visible when the background is flat, opaque, or low-contrast. Layered colors, gradients, and soft blobs make the glass effect easier to notice.

Does glassmorphism work in every browser?

Support is strong in current browsers, but older browsers or some device configurations may not apply backdrop-filter. The generated code includes a readable semi-transparent fallback.

How can I make a glass card more readable?

Increase text contrast, reduce panel transparency, simplify the background, or rely more on the solid fallback background behind the frosted layer.

Can I save my favorite styles?

Yes. Saved styles are stored only in your current browser, with a maximum of 12 styles.

Does this tool upload or store my design settings?

No. Customization runs locally in your browser. Saved styles use browser localStorage and are not uploaded to Optisio servers.

Overview

What is glassmorphism?

Glassmorphism is an interface style that layers translucent surfaces over a visual background. It commonly combines a semi-transparent background, backdrop blur, a subtle border, rounded corners, and soft shadows to create a frosted-glass appearance.

How to use

From preview to production CSS

01
Choose a preset or start with the default style.
02
Adjust the background, glass transparency, blur, border, shadow, and corners.
03
Preview the card at different settings and check its readability.
04
Copy CSS, HTML, or a full standalone demo.
05
Replace the example content and integrate it into your website.

Tips

Glassmorphism design tips

Use a visually interesting background; blur is more noticeable over layered colors or shapes.
Keep the glass panel slightly transparent so it still looks like glass.
Use high text contrast and avoid low-opacity text.
Limit blur and shadow intensity to preserve readability and performance.
Use glass surfaces sparingly for focal cards, dialogs, or navigation—not every element on a page.
Test on mobile and on a non-glass fallback background.

Compatibility

Browser compatibility note

Glass effects typically rely on backdrop-filter. Modern browsers support it, but older browsers or some device configurations may not. The generated code includes a readable semi-transparent background fallback, so content should remain usable even without the blur effect.

Implementation

How to add the CSS to your website

Plain HTML/CSS

Copy the HTML and CSS, paste the CSS into your stylesheet, then insert the HTML into the page body.

WordPress

Add CSS in Appearance → Customize → Additional CSS or your theme/site-builder custom CSS area, then add HTML in a Custom HTML block. Exact wording can vary by theme.

Next.js / React

Place CSS in a CSS module, global stylesheet, or component styles. Convert class to className when using JSX.
