HTML class
One small loader script, then an <i> tag. The page downloads only the icons it shows, in any mix of styles. The icon takes the current text colour and font size.
Paste it
<script src="https://cdn.jsdelivr.net/npm/@withicons/classes@latest/dist/with-loader.js" defer></script> <i class="with with-lightbulb"></i> <!-- line --> <i class="with with-lightbulb with-solid"></i> <!-- also with-duo, with-gloss, with-engrave, with-blueprint, with-sketch, with-glass, with-kawaii, with-sticker, with-pixel, with-retro, with-luxe, with-bauhaus, with-skeuo, with-anime, with-gothic, with-pastel, with-coquette, with-plush, with-clay, with-bento, with-suite, with-dock, with-liquid, with-chrome, with-soft3d, with-brutal, with-utsav, with-rangoli, with-halloween, with-christmas, with-lunar, with-valentine -->
Make it bigger or smallerfont size, a size class or an exact size
The icon is 1em square, so it follows the text size. Three ways to make it 48 px:
Font size also grows with the text around it
<i class="with with-lightbulb" style="font-size: 48px"></i>A size class with-xs, with-sm, with-lg, with-2x to with-5x: times the text size
<i class="with with-lightbulb with-3x"></i>An exact size whatever the text size
<i class="with with-lightbulb" style="--with-size: 48px"></i>Setting only height does not work: the width stays 1em.
Good to know
The loader is about 6 KB gzipped and links just the CSS of the icons on the page (a line icon is about 270 bytes gzipped). No JavaScript? Link with-base.css and line/lightbulb.css from @withicons/classes yourself, or a whole style per file: with-line.css (all 734 line icons, about 26 KB gzipped). with-all.css (every style, about 6.3 MB gzipped) is for prototypes only. Add role="img" and aria-label when the icon carries meaning on its own.

<with-icon name="lightbulb" size="48"></with-icon>Good to know
The page downloads only what it shows: about 7 KB gzipped for the element, then one small file per icon and style. Unique aliases resolve too: <with-icon name="idea"> renders lightbulb.
SVG / CDN
Every style as a standalone 24×24 file. An <img> can’t inherit currentColor, so paste the markup inline when you need to recolour.
Paste it
<img src="https://cdn.jsdelivr.net/npm/@withicons/core@latest/dist/svg/line/lightbulb.svg" width="24" height="24" alt="Lightbulb"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="1.75" stroke-linecap="round" stroke-linejoin="round"><path d="M9 15.5 C9 13.75 5 12.25 5 9 A7 7 0 0 1 19 9 C19 12.25 15 13.75 15 15.5 Z"/><path d="M9 15.5 V19 A2 2 0 0 0 11 21 H13 A2 2 0 0 0 15 19 V15.5"/><path d="M12 15.5 V12.5 M9.75 10.25 L12 12.5 L14.25 10.25" class="wm-a"/></svg>

<img src="https://cdn.jsdelivr.net/npm/@withicons/core@latest/dist/svg/line/lightbulb.svg" width="48" height="48" alt="">Motion
Optional animations, imported separately. They move the element around the icon, so they work with every style and every package. This icon’s own animation glows softly as its filament flickers on, like an idea.
Install
npm i @withicons/motionUse it
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@withicons/motion@latest/dist/motion.css"> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@withicons/motion@latest/dist/icons/lightbulb.css"> <!-- this icon's own moves --> <!-- always moving: glow --> <span class="wm wm-loop" data-wm="lightbulb"><i class="with with-lightbulb"></i></span> <!-- moves when the button is hovered or focused: glow --> <button class="wm-trigger"><span class="wm wm-hover" data-wm="lightbulb"><i class="with with-lightbulb"></i></span> Lightbulb</button> <!-- click to turn lightbulb into lightbulb (solid): the button's aria-pressed decides the icon.

On its own: wm-swap-auto (+ --wm-swap-hold) --> <button class="wm-trigger" type="button" aria-pressed="false" aria-label="Lightbulb" onclick="this.setAttribute('aria-pressed', this.getAttribute('aria-pressed') !== 'true')"> <span class="wm-swap wm-fx-fade"> <i class="with with-lightbulb wm-a"></i> <i class="with with-lightbulb with-solid wm-b"></i> </span> </button>
Good to know
motion.css holds the presets (about 10 KB gzipped). Each icon’s own moves are a file of their own (about 0.3 KB gzipped); icons.css bundles all 734 (about 18 KB gzipped) for bundled apps. Pick another move with wm-p-<preset> (32 presets) and tune it with --wm-dur and --wm-k. JavaScript: import { motion, swap } from '@withicons/motion'. Everything stops for visitors who ask for reduced motion.
