How it works

  1. 1
    Pick a background

    Choose a preset gradient or drop your own image - the glass sits on top.

  2. 2
    Tune the sliders

    Blur, saturation, background alpha, border, radius, shadow - the preview updates instantly.

  3. 3
    Copy the CSS

    Paste into your stylesheet or Tailwind arbitrary-values ([backdrop-filter:blur(20px)]).

Frequently asked questions

Do all browsers support backdrop-filter?

Yes on Chromium, Safari, and modern Firefox. Older Firefox needs a fallback background color - the generated CSS includes one.

Why is my glass showing solid?

backdrop-filter only works when the element has translucent background. Keep the background alpha below 1 and make sure there's actual content behind the card.

Does this work in Tailwind?

Yes - Tailwind ships backdrop-blur-* utilities. The generator shows both raw CSS and the closest Tailwind class combo.
