Frequently asked questions

What CSS property creates the glassmorphism effect?

backdrop-filter: blur() plus a semi-transparent background. Saturation on the filter makes colors behind the glass look more vivid. A light border and soft shadow finish the frosted-glass look.

Does glassmorphism work in Firefox?

Firefox still has limited backdrop-filter support in some setups. The Pure CSS export includes an @supports fallback that uses a more opaque background when blur is not available.

How do I add glassmorphism in Tailwind CSS?

Copy the Tailwind tab. It uses arbitrary values such as backdrop-blur-[12px] and bg-[rgba(...)] so the classes match the preview without a custom plugin.

Is glassmorphism bad for performance?

Large blurred areas can be expensive to paint. Keep blur moderate, avoid stacking many glass layers, and test on lower-end devices. Prefer this effect on cards, nav bars, and modals rather than full-page backgrounds.

Yes. It runs in your browser with no signup. Colors and CSS stay on your device.
