Glassmorphism CSS Generator

Create the frosted-glass look with live sliders for blur, transparency, color, saturation, border and shadow. Drag the card over a colorful background or your own image, then copy clean CSS, Tailwind classes or a ready HTML snippet.

How to use the Glassmorphism CSS Generator

1. Pick a preset or start from the default frosted card.
2. Move the sliders: blur softens what is behind the card, transparency sets how much tint shows, saturation makes colors behind it pop.
3. Change the background or upload an image to test the effect on your real design. Drag the card to see it over different areas.
4. Adjust the border and shadow to give the glass a crisp edge and depth.
5. Copy the CSS, Tailwind classes or HTML snippet and paste it into your project.

How the glass effect works

Four CSS properties work together. background with an alpha value (for example rgba(255, 255, 255, 0.2)) gives the light tint. backdrop-filter: blur() blurs everything painted behind the element, which creates the frosted look, and saturate() in the same filter boosts the colors that shine through. A thin, semi-transparent white border imitates the light catching the glass edge, and a soft box-shadow lifts the card off the page.

Design tips

• Give it something to blur. Glass only reads as glass over color: gradients, blurred shapes or photos. On a plain white page it just looks gray.
• Keep text readable. Increase the tint opacity or switch to dark glass with light text when the background is busy. Aim for a contrast ratio of at least 4.5:1 for body text.
• Use it sparingly. Glass works best for a few floating layers such as navigation bars, modals and cards, not for every element.
• Provide a fallback. Wrap the effect in @supports (backdrop-filter: blur(1px)) { … } and use a more opaque background otherwise, and consider @media (prefers-reduced-transparency: reduce) where supported.
