Animated Smile icon for React.

A face that blinks and then breaks into a wider smile.

What you hear. A little blink tick, then a giggle of three rising bubbly notes as the smile widens. Every note lands on a beat of the animation.

Use it

This is how you would use it. The file itself comes with Pro; the snippet follows everything you change on the stage.

TSXpage.tsx
import { SmileIcon } from "@/components/icons/smile";
 
export default function Page() {
  return (
    <SmileIcon size={104} accent="#ff9f0a" />
  );
}

Spark just sets the accent prop, so the small details of each icon get their own colour.

Where to use the smile icon

4 real places it fits, each one live. Hover, tap or press a key on a mock-up to see the icon move in context, then copy the file above and drop it in.

  • Add emoji

    Emoji picker

    The face blinks and widens its smile when you reach for emoji.

  • Feedback prompt

    Leads a quick satisfaction survey.

  • Mood tag

    A mood or sentiment label.

  • Thanks for the feedback!We love hearing from you.

    Thanks message

    Warms up a confirmation.

More in context on the Made for real interfaces page: a player, a cart, a toolbar, a chat box and a tab bar.

The code

One file. Save it as components/icons/smile.tsx, run npm i framer-motion, and import SmileIcon.

The Smile code is part of Pro

Preview and play it above, with its looks and its sound. Pro unlocks the file to copy for every Pro icon.

The sound (optional)

A little blink tick, then a giggle of three rising bubbly notes as the smile widens. It is written against this icon's own animation: each line below is a note placed on a beat of the picture, and t() stretches it with the speed prop. There are no audio files: it is synthesised in the browser.

  1. Once per project, copy sound-engine.ts and sound-kit.ts from the sound guide into components/icons/.
  2. Save the score below as components/icons/sounds/smile.ts.
  3. Call playIconScore(smile) from a click or hover handler:
"use client";
 
import { SmileIcon } from "@/components/icons/smile";
import * as smile from "@/components/icons/sounds/smile";
import { playIconScore } from "@/components/icons/sound-engine";
 
export function SmileButton() {
  return (
    <button
      type="button"
      onPointerEnter={() => playIconScore(smile)}
      onClick={() => playIconScore(smile)}
    >
      <SmileIcon size={24} />
    </button>
  );
}

sizenumber24Width and height in pixels.
strokeWidthnumber2Line thickness, in a drawing that is 24 units wide.
speednumber1Playback speed: 1 is the designed pace, 2 is twice as fast, 0.5 is half.
accentstringcurrentColorColour of the icon's small accent details (a badge, a spark, a trail). Left out, they match the icon.
classNamestring–Set a text colour here: the icon draws in currentColor.
playboolean–true plays, false rests. Left out, it follows the pointer (or loops, for loaders).

Looks (optional)

Wrap an icon, or a whole grid of them, in IconMaterial to give it a finish: neon glow, an aurora spectrum, polished chrome, or one of the liquid looks (Mercury, Liquid and Glass), which are pure SVG with no canvas or WebGL and each make a sound of their own. Save it as components/icons/icon-material.tsx. Spark needs no helper: it is just the accent prop.

"use client";
 
import { useId, type CSSProperties, type ReactNode } from "react";
import { useReducedMotion } from "framer-motion";
 
export type IconMaterialName = "line" | "spark" | "neon" | "aurora" | "chrome" | "mercury" | "liquid" | "glass";
 
/**
 * Looks for the icons: wrap one icon, or a whole grid of them, and they all take on the same finish.
 *
 *   line     plain strokes in the current colour (the default; nothing is added)
 *   spark    strokes in the current colour, with each icon's small accent details in colour:
 *            give the icons an `accent`, e.g. <BellIcon accent="#ff3b30" />
 *   neon     a glow around every stroke, in the current colour
 *   aurora   every stroke painted with a blue-to-orange spectrum
 *   chrome   every stroke painted as polished metal (looks best on a dark background)
 *   mercury  liquid metal: the strokes round and thicken into a lit tube, and a reflected room of light and
 *            dark bands flows slowly along them (best on a dark background)
 *   liquid   the strokes in the current colour as a wet droplet: where they touch they melt together, with a
 *            glossy highlight, and the whole icon wobbles like jelly while the pointer is over it
 *   glass    clear glass: a translucent body with a bright edge, a fringe of red and blue where the lens bends
 *            the light, and a sheen that drifts across (best on a dark or colourful background)
 *
 * It only restyles, so it works with any icon that draws in currentColor and has a 24-unit viewBox. The three
 * liquid looks are pure SVG (gradients and filters): no canvas, no WebGL, nothing to load, and they hold still
 * for visitors who have reduced motion switched on.

Questions about the smile icon

How do I use the smile icon in React?

Copy smile.tsx into your project, install framer-motion, and import SmileIcon. Render it like any component: <SmileIcon size={32} />.

Where can I use the smile icon?

emoji picker, feedback prompt, mood tag, thanks message. Each one is shown live on this page.

Is the smile icon free?

You can preview and play the smile icon, with its looks and its sound, for free. Its code and sound file are part of Nexus UI Pro, which unlocks all 125 Pro icons. 75 other icons are free to copy.

Does it need a library?

Only Framer Motion, which draws the animation. The icon itself is one file of plain SVG and React, with no other dependencies.

Can I change the size and colour?

Yes. Set size (in pixels) and strokeWidth as props. The icon draws in currentColor, so a text colour class on it, or on a parent, changes its colour.

Does the smile icon make a sound?

Yes, optionally: A little blink tick, then a giggle of three rising bubbly notes as the smile widens. The sound is scored against the icon's own animation, so every note lands on a beat of the picture, and it follows the speed prop. It plays only if you call it, and it follows the visitor's sound setting.

What happens with reduced motion?

When the visitor has reduced motion switched on in their system, the icon does not animate. It stays in its resting pose.
