glassy-liquid

Apple-style Liquid Glass for the web: real refraction, the core iOS 26 Liquid Glass controls, and typed bindings for Web Components, React, Vue, and Svelte.

Docs, live demos, and the playground: https://9und30.github.io/glassy-liquid/

Why glassy-liquid

• The core iOS 26 Liquid Glass controls. Buttons, switches, sliders, a tab bar, a segmented control, menus, toolbars, search, sheets, and scroll-edge blur, plus a generic surface and a scene. Nineteen components, one look.
• Safari, iOS, and Firefox included. Chromium refracts the live page. Inside <glass-scene>, WebKit and Firefox refract photos, video, and DOM through WebGL or a scoped content filter. Every other engine gets a calibrated frost with the same rim light, tint, shadow, and motion.
• Accessible by default. prefers-reduced-motion drops the elasticity, prefers-reduced-transparency makes the material opaque, and forced colors switch to system colors. Prominent labels stay at a 4.5:1 contrast.
• About 35.7 kB gzip. dist/glassy-liquid.min.js is 35.7 kB gzip and registers every element. Zero runtime dependencies. No WebGPU.
• Web Components, React, Vue, and Svelte. One binding table in src/bindings/specs.ts drives all three frameworks. A parity test keeps them 1:1.

Not affiliated with Apple. Liquid Glass names the design language this library recreates.

Quick start

# snippet: install
npm install glassy-liquid

With a bundler such as Vite, register the elements once, then write HTML. Without a build step, use the CDN module shown below instead: a bare import "glassy-liquid/elements" only resolves through a bundler or an import map. Wrap a photograph in <glass-scene> so Safari, iOS, and Firefox refract it too. src accepts any image URL. The photograph below is public, so the example works when pasted. If the image fails, the scene hides the broken icon and keeps linear-gradient(160deg, #9bb7c9, #e7eef2).

<!-- snippet: quick-start -->
<script type="module">
  import "glassy-liquid/elements";
</script>

<glass-scene src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg/960px-Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg" style="height: 100vh; background: linear-gradient(160deg, #9bb7c9, #e7eef2)">
  <glass-button variant="prominent">Continue</glass-button>
</glass-scene>

React 18 or 19. In the Next.js App Router this component uses state, so its file starts with "use client":

"use client";
// snippet: react-settings
import { useState } from "react";
import { GlassScene, GlassButton, GlassSwitch, GlassSlider } from "glassy-liquid/react";

export function Settings() {
  const [wifi, setWifi] = useState(true);
  const [level, setLevel] = useState(50);
  return (
    <GlassScene src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg/960px-Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg" style={{ height: "100vh", background: "linear-gradient(160deg, #9bb7c9, #e7eef2)" }}>
      <GlassSwitch checked={wifi} onCheckedChange={setWifi} aria-label="Wi-Fi" />
      <GlassSlider value={level} onValueChange={setLevel} />
      <GlassButton variant="prominent">Done</GlassButton>
      <p className="readout">{wifi ? "on" : "off"} {Math.round(level)}</p>
    </GlassScene>
  );
}

Without a build step, load the single module from a CDN. The path matches the glassy-liquid/cdn export (dist/glassy-liquid.min.js):

<!-- snippet: cdn -->
<script type="module" src="https://cdn.jsdelivr.net/npm/glassy-liquid@0.1/dist/glassy-liquid.min.js"></script>

<glass-surface radius="28" style="padding: 20px">
  Hello, glass.
</glass-surface>

Usage

Web Components

import "glassy-liquid/elements" defines every tag. Attributes are kebab-case (light-angle for lightAngle). Listen for the DOM events in the API reference (change, input, select, toggle, search, detent) plus native click.

React

Import from glassy-liquid/react. Callback props are onCheckedChange, onValueChange, onValueCommit, onSelect, onOpenChange, onSearch, and onDetentChange. Uncontrolled initial values are defaultChecked and defaultValue. The ref is the custom element.

useGlass turns any element into glass:

// snippet: use-glass
import { useRef } from "react";
import { useGlass } from "glassy-liquid/react";

export function Card() {
  const ref = useRef<HTMLDivElement>(null);
  useGlass(ref, { radius: 28 });
  return <div ref={ref} className="card">Card</div>;
}

Vue

Vue 3. Same components and prop names as React. Each framework is an optional peer dependency.

<!-- snippet: vue-settings -->
<script setup lang="ts">
import { ref } from "vue";
import { GlassScene, GlassSwitch, GlassSlider, GlassButton } from "glassy-liquid/vue";

const wifi = ref(true);
const level = ref(50);
function save(value: number) {
  level.value = value;
}
function done() {
  wifi.value = false;
}
</script>

<template>
  <GlassScene src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg/960px-Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg" style="background: linear-gradient(160deg, #9bb7c9, #e7eef2)">
    <GlassSwitch v-model:checked="wifi" aria-label="Wi-Fi" />
    <GlassSlider v-model:value="level" @value-commit="save" />
    <GlassButton variant="prominent" @click="done">Done</GlassButton>
    <p class="readout">{{ wifi ? "on" : "off" }} {{ Math.round(level) }}</p>
  </GlassScene>
</template>

• Callback props work as props or listeners: :onValueChange="fn" and @value-change="fn".
• Two-way binding: v-model:checked, v-model:value, and v-model:open on the components listed in Two-way bindings.
• useGlass(elRef, options) matches the React hook.
• The custom element is el on the component ref.

When you write raw <glass-*> tags in a Vue template (the wrapper components do not need this), tell the compiler they are custom elements:

// snippet: vue-custom-element
export const vuePluginOptions = {
  template: { compilerOptions: { isCustomElement: (tag: string) => tag.startsWith("glass-") } },
};

Pass vuePluginOptions to @vitejs/plugin-vue.

Svelte

Svelte 5 and Svelte 4. The components ship as .svelte source (svelte export condition) and your bundler compiles them. They use export let and <slot> on purpose: that syntax compiles in both versions, and Svelte 5 accepts it without deprecation warnings.

<!-- snippet: svelte-settings -->
<script>
  import { GlassScene, GlassSwitch, GlassSlider } from "glassy-liquid/svelte";
  let wifi = true;
  let level = 50;
  function save(value) {
    level = value;
  }
</script>

<GlassScene src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg/960px-Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg" style="background: linear-gradient(160deg, #9bb7c9, #e7eef2)">
  <GlassSwitch bind:checked={wifi} aria-label="Wi-Fi" />
  <GlassSlider bind:value={level} onValueCommit={save} />
  <p class="readout">{wifi ? "on" : "off"} {Math.round(level)}</p>
</GlassScene>

In a Svelte 5 runes file, use $state instead of let for those bindings. Named slots match HTML: <GlassButton slot="trigger"> inside <GlassMenu>, and <svg slot="icon"> inside <GlassButton> or <GlassMenuItem>. bind:element is the custom element.

Without the components, apply React prop names with the glassProps action:

<!-- snippet: svelte-actions -->
<script>
  import "glassy-liquid/elements";
  import { glassProps, useGlass } from "glassy-liquid/svelte/actions";
  let wifi = true;
</script>

<glass-switch use:glassProps={{ checked: wifi, onCheckedChange: (v) => (wifi = v) }} aria-label="Wi-Fi"></glass-switch>
<div class="card" use:useGlass={{ radius: 28 }}>Glass card</div>

Importing glassy-liquid/svelte also types every <glass-*> tag for svelte-check. With SSR and raw elements, add defer-hydration on each tag. glassProps removes it after hydration. The components do that for you.

Scenes

Chromium refracts whatever is behind the element. WebKit drops backdrop-filter when the list contains a url() SVG filter reference (bug 245510). Firefox does not refract the live page backdrop either. A scene tells the glass what lies behind it:

<!-- snippet: scenes -->
<glass-scene src="https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg/960px-Iceberg_reflection_in_J%C3%B6kuls%C3%A1rl%C3%B3n_%28Unsplash%29.jpg">
  <glass-button variant="prominent">Continue</glass-button>
</glass-scene>

<glass-scene>
  <article glass-backdrop>
    <h2>Live DOM</h2>
  </article>
  <glass-surface radius="capsule"></glass-surface>
</glass-scene>

An image, video, or canvas backdrop is drawn with one shared WebGL context. Any other backdrop is a scoped content filter (keep those scenes small; the work is on the CPU in WebKit). Chromium ignores the scene and keeps the backdrop path unless the scene has force.

Your own elements

// snippet: glass-api
import { glass } from "glassy-liquid";

const card = document.querySelector(".card");
const surface = glass(card, { radius: 28, material: "clear" });
surface.set({ tint: "#0a84ff" });

surface.engine is "backdrop", "scene-gl", "scene-dom", or "css". Call surface.destroy() when the element goes away.

// snippet: custom-element
import { GlassElement } from "glassy-liquid";

class NowPlaying extends GlassElement {
  static glassDefaults = { radius: 30, material: "clear" };
  static interactive = true;
  static extraAttributes = ["title"];
  static styles = ":host { display: flex; gap: 14px; padding: 12px 18px; color: #fff; }";

  render() {
    return `<b></b><slot></slot>`;
  }

  setup() {
    const title = this.shadow.querySelector("b");
    if (title) title.textContent = this.getAttribute("title") ?? "";
  }
}

customElements.define("now-playing", NowPlaying);
document.body.insertAdjacentHTML("beforeend", '<now-playing title="Caustic Hour"></now-playing>');

In TypeScript, type the defaults so the literal values stay narrow: static glassDefaults: GlassOptions = { radius: 30, material: "clear" }; with import type { GlassOptions } from "glassy-liquid".

Lower-level pieces, all exported from glassy-liquid:

• GlassSurface / glass(): the layer stack and renderer selection
• ThumbLens: the solid thumb that lifts into a magnifying lens
• attachPress(): swell, illumination, and gel release
• Spring, springs, rubberBand: analytic springs
• place(), lerpRect(): popover placement and morph geometry
• addTask(), wake(): the shared frame ticker, which sleeps when idle

SSR and hydration

The React, Vue, and Svelte bindings server-render each element with a defer-hydration attribute (the same idea as Lit). While it is present the element stays inert: it does not add role, tabindex, or styles before the framework hydrates. The binding removes the attribute after hydration. That avoids hydration mismatches, including when the elements are registered before hydration. Covered by renderToString + hydrateRoot (React 18 and 19 render without server warnings), Vue createSSRApp, and Svelte 4/5 SSR.

Every entry point is safe to import on the server, including glassy-liquid and glassy-liquid/elements. Custom elements register only in the browser, where customElements exists. glass(), useGlass(), and attachPress() touch the DOM, so call them in an effect or in onMount.

The image created for <glass-scene src> lives in the scene shadow root. Style it with glass-scene::part(backdrop). It is not a light-DOM child, so hydration does not see an extra node.

API reference

Generated from src/bindings/specs.ts. npm test fails if this section drifts from the specs, from the slots in the component source, or from the Svelte slot map.

Glass attributes

These props are accepted on every framework component. They change the material on <glass-surface>, <glass-button>, <glass-group>, <glass-tab-bar>, and <glass-search>. <glass-sheet> applies material, blur, and tint to its slab, including through ::part(glass). glass() and useGlass() take the same fields, plus zoom (default 1), backdrop (default true), and fill.

Framework components also forward class, style, and other DOM attributes, and take children for the default slot. React refs and Vue el point at the custom element. Svelte uses bind:element.

Components

GlassScene

Custom element: <glass-scene>. Real refraction for Safari, iOS, iPadOS, and Firefox. Chromium keeps the faster page-backdrop path unless force is set.

Slots: default.

Parts: ::part(backdrop).

• The automatic src image is not a light-DOM child. Style it with glass-scene::part(backdrop).
• With no src and no backdrop selector, that direct child is the backdrop. An image, video, or canvas uses WebGL. Any other element uses the DOM content filter.
• Glass anywhere inside the scene, including inside shadow roots, picks the scene up on its own.

GlassSurface

Custom element: <glass-surface>. Generic slab for cards, widgets, and bars. The default radius is 24.

No component-specific props.

Slots: default.

Parts: ::part(glass).

• Accepts every glass attribute. Content goes in the default slot.

GlassButton

Custom element: <glass-button>. iOS 26 glass button. prominent fills with the accent, plain draws no glass of its own.

Slots: default, icon, trailing.

Parts: ::part(label), ::part(glass).

• Native event: click. Enter and Space activate the button.
• Slots: icon, then the default slot (the label), then trailing.
• Form-associated. Inside a form, type="submit" calls requestSubmit() and type="reset" resets.
• Accepts every glass attribute. Default radius is capsule. interactive is on.

GlassSwitch

Custom element: <glass-switch>. Toggle whose thumb lifts into a lens. Form-associated, role switch.

Slots: none.

Parts: ::part(track), ::part(fill), ::part(thumb), ::part(glass).

• Also fires input on a user toggle.
• Keyboard: Space and Enter toggle. A wrapping <label> activates it.
• Vue: v-model:checked. Svelte: bind:checked.

GlassSlider

Custom element: <glass-slider>. Slider with a thumb that magnifies into a lens while dragged. Form-associated, role slider.

Slots: none.

Parts: ::part(track), ::part(fill), ::part(ticks), ::part(thumb), ::part(glass).

• Keyboard: Arrow keys nudge, Home and End jump to the ends.
• Vue: v-model:value. Svelte: bind:value.

GlassTabBar

Custom element: <glass-tab-bar>. Floating tab bar. The selection is a pill that lifts into a draggable magnifying lens.

Slots: default.

Parts: ::part(indicator), ::part(lens), ::part(glass).

• Children are <glass-tab> elements in the default slot.
• Role tablist. Arrow keys, Home, and End move the selection.
• Accepts every glass attribute. Default radius is capsule.
• Vue: v-model:value. Svelte: bind:value.

GlassSegmented

Custom element: <glass-segmented>. Segmented control with the same selection lens, on a quiet frosted track.

Slots: default.

Parts: ::part(track), ::part(indicator), ::part(lens), ::part(glass).

• Children are <glass-segment> elements in the default slot.
• The track itself is not a glass surface. Only the lens is.
• Vue: v-model:value. Svelte: bind:value.

GlassTab

Custom element: <glass-tab>. One item in a <glass-tab-bar>. Role tab.

Slots: default.

Parts: ::part(content).

• The default slot is the label, often an icon plus text.

GlassSegment

Custom element: <glass-segment>. One item in a <glass-segmented>. Role tab.

Slots: default.

Parts: ::part(content).

• The default slot is the label.

GlassMenu

Custom element: <glass-menu>. Pull-down menu that morphs out of its trigger. Press, drag, and release selects in one gesture.

Slots: default, trigger.

Parts: ::part(panel), ::part(content), ::part(glass).

• Put the trigger in the trigger slot. Items, labels, and separators go in the default slot.
• The panel is glass. Set the element's glass property (GlassOptions) to tune that surface. It is not a binding prop.
• Vue: v-model:open. Svelte: bind:open.

GlassMenuItem

Custom element: <glass-menu-item>. A row in a menu. Role menuitem, or menuitemcheckbox when checked or checkable is set.

Slots: default, icon, shortcut.

Parts: ::part(label).

• Slots: the default slot is the label, plus optional icon and shortcut. Put icons in icon: they trail the row at 20px, as on iOS. An SVG or image in any slot is capped at 20px.

GlassMenuSeparator

Custom element: <glass-menu-separator>. A hairline between menu rows. Role separator.

No component-specific props.

Slots: none.

Parts: none.

• No props and no slots.

GlassMenuLabel

Custom element: <glass-menu-label>. A section header inside a menu. Role presentation.

No component-specific props.

Slots: none.

Parts: none.

• The label is light-DOM text. The element has no shadow slot.

GlassToolbar

Custom element: <glass-toolbar>. A row of buttons and groups with arrow-key focus. Role toolbar. The bar itself is not glass.

No component-specific props.

Slots: none.

Parts: none.

• No slots.

GlassSearch

Custom element: <glass-search>. Search field on a glass capsule, with a clear button. Form-associated.

Slots: default.

Parts: ::part(icon), ::part(input), ::part(clear), ::part(glass).

• Also fires a native change event from the inner input.
• Escape clears the field when it has text.
• The default slot is trailing content after the clear button.
• Accepts every glass attribute. Default radius is capsule.
• Vue: v-model:value. Svelte: bind:value.

Slots: default.

Parts: ::part(scrim), ::part(sheet), ::part(grabber), ::part(body), ::part(glass).

• The default slot is the sheet body.
• small is 25vh, medium is 50vh, large fills the viewport inset.

GlassProgressiveBlur

Custom element: <glass-progressive-blur>. iOS 26 scroll-edge blur. Content fades into a stronger blur toward one edge. aria-hidden.

Slots: none.

Parts: none.

• Position it yourself (position: fixed or absolute over the scrolling content).
• prefers-reduced-transparency: reduce removes the blur.

Two-way bindings

Vue v-model:* and Svelte bind:* follow the same events as the React change callbacks:

• GlassSwitch: v-model:checked / bind:checked
• GlassSlider: v-model:value / bind:value
• GlassTabBar: v-model:value / bind:value
• GlassSegmented: v-model:value / bind:value
• GlassMenu: v-model:open / bind:open
• GlassSearch: v-model:value / bind:value
• GlassSheet: v-model:open / bind:open

Theming

/* snippet: theme */
:root {
  --glass-accent: #0a84ff;
  --glass-appearance: dark;
  --glass-font: "Inter", system-ui;
}

With appearance="auto" (the default), glass follows --glass-appearance, then the page color scheme, the way native form controls do. A page that never declares color-scheme: dark or color-scheme: light dark (in CSS or <meta name="color-scheme">) keeps light glass in OS dark mode, so text you color yourself stays readable. Pages that support both schemes follow the OS. Theme switches on <html> or <body> (class, attribute, or style) and the meta tag are picked up automatically. After changing --glass-appearance or color-scheme on another element, call updateAppearance().

Glass sets --gl-fg and --gl-text-shadow on the host and both inherit. For content you color yourself inside glass, use color: var(--gl-fg). Every glass element sets data-appearance="light" or data-appearance="dark".

Component knobs, each with a built-in default:

--glass-button-height, --glass-button-padding, --glass-button-font-size, --glass-on-accent, --glass-accent-text, --glass-switch-on, --glass-switch-off, --glass-slider-track, --glass-slider-off, --glass-thumb, --glass-tab-bar-height, --glass-tab-selection, --glass-tab-selected, --glass-segmented-height, --glass-segmented-track, --glass-segmented-backdrop, --glass-segmented-selected, --glass-segmented-thumb, --glass-selector-padding, --glass-item-direction, --glass-item-gap, --glass-menu-highlight, --glass-destructive, --glass-search-height, --glass-scrim, --glass-sheet-inset, --glass-sheet-max-width, --glass-sheet-padding, --glass-group-padding, --glass-toolbar-gap.

Style internals with ::part(), listed per component in the API reference. The shared glass stack is ::part(glass). The scene backdrop image is glass-scene::part(backdrop).

Accent colors move to a readable lightness per appearance where the browser supports relative color syntax. Older browsers keep the accent as given. Prominent buttons darken the accent just enough for a 4.5:1 white label. Clear glass puts a soft halo behind its light text.

Browser support

Accessibility

Real roles and states: button or link, switch, slider, tablist / tab, menu / menuitem / menuitemcheckbox, toolbar, dialog. Keyboard support matches those roles (Enter and Space, arrows, Home and End, Escape to dismiss). Focus rings are visible. Switch, slider, search, and submit buttons are form-associated.

prefers-reduced-motion: reduce removes elastic stretch and snaps sheets, menus, and thumbs. prefers-reduced-transparency: reduce makes the glass material opaque and drops scroll-edge blur. forced-colors: active uses Canvas / CanvasText and hides the decorative rim.

Performance

Measured with npm run bench on 2026-10-15 (bench/results.json). Same scene in both libraries, 16 glass surfaces over a photo with live text, headless Chrome 154 with GPU, device pixel ratio 2, median of 3 runs. On this machine glassy-liquid's frame time sat on a 16.7 ms interval (60 fps) in every case. Bundle sizes for both libraries are gzip level 9 in SI kilobytes (1 kB = 1000 bytes), the way size-limit measures.

Nine-slice maps never re-encode on resize. Shadows and rims are cached images. One shared ticker runs only while something animates. Offscreen scenes do no work. WebGL scenes share one context and one texture per image URL. Chromatic dispersion is off by default on the backdrop path because splitting color channels costs several GPU passes per surface. Set dispersion on the surfaces where you want it. The CDN bundle (dist/glassy-liquid.min.js) is 35.7 kB gzip.

Coming from liquid-glass-react

liquid-glass-react is a single React wrapper that refracts its backdrop with an SVG displacement filter. glassy-liquid is a control library: the same material, plus the iOS 26 controls, Web Component / Vue / Svelte bindings, and a scene path for Safari and Firefox.

// snippet: migrate
import { GlassSurface } from "glassy-liquid/react";

export function ClickMe() {
  return (
    <GlassSurface radius={100} refraction={64} blur={8} dispersion={0.2} interactive>
      <span>Click Me</span>
    </GlassSurface>
  );
}

On Safari and Firefox, put that surface inside <GlassScene src="..."> (or a DOM backdrop) so the refraction is real. Chromium refracts the page without a scene.

FAQ

Does it need WebGPU? No. Chromium uses SVG backdrop filters. Scenes use WebGL. The fallback is CSS backdrop-filter.

Why is Safari frosted until I add a scene? WebKit does not apply SVG filters inside backdrop-filter, so no library can bend arbitrary page content there. <glass-scene> names the backdrop and refracts that.

Can I use it in a React Server Component? The React entry starts with "use client", so the components render from a Client Component, and Next.js also renders those on the server. Server rendering plus hydration is supported, and every entry point is safe to import on the server. See SSR and hydration.

Do I have to install React, Vue, and Svelte? No. They are optional peer dependencies. Install the one you use.

How big is the CDN build? dist/glassy-liquid.min.js is 35.7 kB gzip and registers every element. Framework bindings are separate entry points, so a React app does not download the Vue build.

Can a coding agent read these docs? Yes. The package ships dist/docs/llms.txt (overview, setup, and the export map) and dist/docs/llms-full.txt (plus this API reference and every component in every framework), generated from the same sources as the docs site. The docs site serves the same files at https://9und30.github.io/glassy-liquid/llms.txt and https://9und30.github.io/glassy-liquid/llms-full.txt. To point an agent at the installed version, add a line like this to your project's AGENTS.md: "Before writing glassy-liquid code, read node_modules/glassy-liquid/dist/docs/llms-full.txt."

Will prefers-reduced-motion turn the effect off? It removes elasticity and snap animations. The glass material stays. prefers-reduced-transparency is what makes the material opaque.
