Questions fréquentes

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.
