How to use
- Pick one of the six background gradient presets.
- Adjust the sliders for blur, background opacity, saturation, corner radius, border width and opacity, and inner padding.
- Use the color picker to set the card's tint color and check whether you want a drop shadow.
- Once the preview looks right, hit the copy button under the CSS block and paste the code into your project.
FAQ
- Which browsers support the generated CSS?
- It works in current versions of Chrome, Edge, Safari, and Firefox, all of which support backdrop-filter. The -webkit-backdrop-filter prefix is included as well for Safari.
- My card just looks hazy — I don't see any glass effect.
- backdrop-filter blurs whatever sits behind the card, so you need a colorful background or an image behind it. Against a flat, solid background there's nothing to refract and the glass look disappears.
- Can I use the generated CSS in a real project?
- Yes. Copy it and use it freely in any project — no attribution or license notice required.
