Icons are visual symbols that represent actions, objects or ideas.
Placer Toolkit comes bundled with over 2 000 free icons courtesy of Font Awesome. These icons are part of the default icon library. If you prefer, you can register custom icon libraries as well as Font Awesome Pro.

The default icon library uses Font Awesome Free, which comes with three icon styles: Solid, Regular and Brands. If you’re a Font Awesome Pro user, you can provide your Kit code to unlock Pro icon packs and styles.
Icons inherit their colour from the current text colour. Thus, you can set the color property on the <pc-icon> element or an ancestor to change the colour.
Icons are sized relative to the current font size. To change the size of an icon, set the font-size property on the icon itself or on a parent element as shown below.
For non‐decorative icons, use the label attribute to announce the label’s content to assistive devices.
By default, Font Awesome icons have a 1em height and a fixed 1em width. Use the auto-width attribute to allow the icon to use its natural variable width.
Images that are supposed to act like icons can be loaded individually with the src attribute. Only SVGs on a local or CORS‐enabled endpoint are supported. If you’re using more than one custom icon, it might make sense to register a custom icon library instead.
You can register additional icons to use with the <pc-icon> component through custom icon libraries. Icon files can exist locally or on a CORS‐enabled endpoint (e.g., a CDN). There is no limit to how many custom icon libraries you can register and there is no cost associated with registering them, as individual icons are only requested when they’re used.
Placer Toolkit ships with two built‐in icon libraries, default and system. The default icon library contains all icons in Font Awesome Free. The system icon library only contains a subset of icons in Font Awesome Free that are used internally by Placer Toolkit components.
To register a custom icon library, use the registerIconLibrary() function exported from utilities/icon-library.js. At a minimum, you must provide a name and a resolver function. The resolver function translates an icon name to a URL where the corresponding SVG file exists. Refer to the examples below to better understand how it works.
Here’s an example that registers an icon library located in the /assets/icons directory.
<script type="module">
import { registerIconLibrary } from "https://cdn.jsdelivr.net/npm/placer-toolkit@1.0.0-alpha.3/cdn/utilities/icon-library.js";
registerIconLibrary("custom-icon-library", {
resolver: (name) => `/assets/icons/${name}.svg`,
});
</script>To display an icon, set the library and name attributes of a <pc-icon> element. The icon-style attribute is not set up for custom icon libraries by default, as it’s designed for the default and system icon libraries.
<!-- This will show the icon located at /assets/icons/face-smile.svg -->
<pc-icon library="custom-icon-library" name="face-smile"></pc-icon>If an icon is used, before registration occurs, it will be initially empty, but shown when it gets registered.
