Glassmorphism Generator

What is a glassmorphism / neumorphism generator?

*Glassmorphism* and *neumorphism* are two surface styles you'll see all over modern web design. **Glass** is the frosted-pane look — a translucent card that blurs whatever sits behind it, often layered over a colorful gradient or photographic backdrop. **Neumorphism** is the soft-plastic look — a card that appears to extrude (or sink) out of its surface, lit by paired light and dark shadows of the same hue as the background.

Both effects are pure CSS — no images, no JavaScript, no libraries. Glass relies on backdrop-filter: blur() plus a translucent fill and a thin border. Neumorphism is built from a pair of box-shadow declarations: one slightly darker than the surface, one slightly lighter, offset in opposite directions. The math is short, but tuning the values by hand until everything sits right takes a while. A generator skips that step.

This tool gives you sliders for every parameter that matters, a preview pane that sits on a configurable backdrop (so the glass effect actually has something to refract), and a one-click copy of the resulting CSS. Everything runs in your browser — paste the snippet straight into your stylesheet.

What you'll learn while playing with these surfaces

• backdrop-filter is the property that powers glassmorphism — it blurs and saturates whatever is *behind* the element, not the element itself.
• Glass needs a translucent fill (rgba(...) with low alpha) and a thin light border to look like real frosted material; remove either and the effect collapses.
• Neumorphism uses **two** box-shadow declarations, not one: a darker shadow on the bottom-right and a lighter highlight on the top-left, both with the surface hue rather than pure black/white.

How to generate a glass or neumorphism surface step by step

1. 1

   Pick the style mode

   Switch between **Glass** and **Neumorphism** at the top. Glass needs a backdrop; neumorphism sits on a flat surface color you control.

2. 2

   Tune the core parameters

   For glass, the big levers are *blur* (how heavily the backdrop is smeared), *background opacity* (how translucent the card is), and *tint* (a faint color cast). For neumorphism, the big levers are *distance* (how far the shadows are offset), *blur* (how soft they are), and *intensity* (how much the light/dark companions differ from the surface).

3. 3

   Choose a backdrop or surface color

   Glass shows best on a punchy gradient or photo. Neumorphism shows best on a soft, slightly off-pure color (#e0e5ec is the canonical "neumorphic grey"). The tool ships with a row of presets you can click.

4. 4

   Switch the neumorphism style

   Neumorphism has three flavors: **Raised** (extruded), **Flat** (same shadows, no gradient fill), and **Inset** (pressed in). Try all three — they share the same shadow math, only the direction changes.

5. 5

   Copy the CSS

   Hit **Copy** and drop the snippet into your stylesheet. The output is production-ready: it includes the vendor-prefixed -webkit-backdrop-filter for older Safari, ordered properties, and the matching border-radius so it works as a single class.

Surface examples to try

background: rgba(255, 255, 255, 0.18);backdrop-filter: blur(14px) saturate(180%);-webkit-backdrop-filter: blur(14px) saturate(180%);border: 1px solid rgba(255, 255, 255, 0.30);border-radius: 16px;box-shadow: 0 8px 32px rgba(0, 0, 0, 0.12);

background: linear-gradient(145deg, #f0f5fa, #cdd1d7);border-radius: 24px;box-shadow:  16px 16px 32px #b8bcc1,  -16px -16px 32px #ffffff;

background: #e0e5ec;border-radius: 24px;box-shadow:  inset 8px 8px 16px #b8bcc1,  inset -8px -8px 16px #ffffff;

Common glass / neumorphism mistakes

• Forgetting -webkit-backdrop-filter. Older Safari (and any embedded WebView) ignores backdrop-filter without the prefix and your glass becomes a solid block.
• Using pure black and white for neumorphic shadows. Real-world neumorphism uses two colors **near** the surface hue — black/white shadows make the card look cheap.
• Putting glass on plain white. There's no color behind the blur, so the effect disappears and you're left with a faintly tinted box. Glass needs a busy backdrop.
