What styles can I generate?

Glassmorphism (frosted glass with backdrop-filter) or neumorphism (soft UI with matching background and dual shadows).

Does the snippet include Safari prefixes?

Yes. It always outputs both backdrop-filter and -webkit-backdrop-filter for Safari through 17.x.

How does Tailwind mapping work?

It prefers named utilities such as backdrop-blur-xl and rounded-2xl, then falls back to arbitrary values. The v3/v4 blur-sm change is flagged.

What happens without backdrop-filter support?

When @supports fallback is on, the snippet uses a near-opaque tint so the card stays readable.

Should I use neumorphism on primary buttons?

No. Shadows do not count toward contrast, so keep neumorphism off primary interactive controls.

Glassmorphism CSS Snippet Builder

End-to-end frosted-glass / neumorphism CSS snippet generator: blur+saturate backdrop, tint, border, layered shadows, grain overlay, @supports fallback, -webkit- prefix, Tailwind mapping and live preview.

Details

What this tool helps you do

Defaults follow the verified 2025 composite (css.glass lineage): rgba tint 0.10–0.30, blur 4–20px with saturate(120–180%) against blur muddiness, 1px rgba border, outer shadow plus inset 0 1px 0 rgba(255,255,255,.3) top highlight. backdrop-filter sits at 95.69% global support; Safari requires -webkit- through 17.x (unprefixed since 18, 2024) and Firefox since 103 — the snippet always emits both declarations. Grain uses an SVG feTurbulence fractalNoise data-URI on ::before at opacity 0.12; @supports not (backdrop-filter) falls back to a near-opaque tint. Tailwind mapping prefers named utilities (backdrop-blur-xl = 24px, rounded-2xl = 16px) and falls back to arbitrary values, with the v3/v4 blur-sm 4px→8px shift flagged. Neumorphism follows neumorphism.io: background matching the page, dark shadow bottom-right + light top-left, inset = pressed, dark mode with light shadow at 0.03–0.1; shadows do not count toward contrast, so keep it off primary controls.

Best-practice frosted glass card (blur 12 / saturate 160)

The 2025 best-practice composite: blur(12px) saturate(160%), white tint at 0.15, 16px radius, 1px border at 0.25, layered shadow with top highlight, grain overlay and @supports fallback — plus the Tailwind mapping with the v4 caveat.

Dark neumorphism control in pressed (inset) state

A dark-mode neumorphism surface (#2d2d2d) with inset shadows for the pressed state, light shadow dimmed to 0.06 so the surface reads as lit — the Tailwind output uses arbitrary shadow values.
