Summary

There are a few ways to get icons from fticons:

1. Use o-icons CSS classes
2. Use o-icons Sass mixins with your own CSS.
3. Request the icon directly from the Image Service (without using o-icons at all).

Markup

To add an icon apply the o-icons-icon class to a span, along with the modifier class for your specific icon e.g. o-icons-icon--arrow-down. See the registry demos for a full list of icons.

<span class="o-icons-icon o-icons-icon--arrow-down"></span>
<span class="o-icons-icon o-icons-icon--audio"></span>
<span class="o-icons-icon o-icons-icon--book"></span>

This will include icons with a 128px width/height by default.

If you would like to use an icon at a different dimension or colour, use o-icon Sass mixins or request the icon from the Image Service directly (without using o-icons at all).

Sass

Includes icons of different sizes and colors

Use oIconsContent to output the styles for an icon of a given size and colour.

The $color argument should be set using an o-colors Sass function such as oColorsByName, but may be set to any hex value.

// Use o-colors so you can use colors from the Origami palette.
@import "o-icons/main";
@import "o-colors/main";

// Output a 32px, claret coloured plus icon.
.my-icon-plus {
	@include oIconsContent(
		$icon-name: 'plus',
		$color: oColorsByName('claret'),
		$size: 32
	);
}

<span class="my-icon-plus"></span>

The oIconsContent mixins outputs styles used by each icon. This is inefficient if your project outputs multiple icons. In this case we recommend outputting the base styles separately with oIconsContentBaseStyles.

// Output a 32px, claret coloured plus icon.
.my-icon {
	@include oIconsContentBaseStyles();
}

.my-icon--plus {
	@include oIconsContent(
		$icon-name: 'plus',
		$color: oColorsByName('claret'),
		$size: 32,
		$include-base-styles: false // do not duplicate the base styles
	);
}

<span class="my-icon my-icon--plus"></span>

o-icons includes a media query to restore either a black or white icon in Microsoft's high-contrast mode. If no icon is acceptable for users of Microsoft's high-contrast mode this may be disabled to reduce bundle size:

.no-high-contrast-window {
	@include oIconsContent(
		$icon-name: 'plus',
		$color: oColorsByName('claret'),
		$high-contrast-fallback: false
	);
}

Using the default CSS helper classes

To output all icon helper classes include the oIcons mixin.

@import "o-icons/main";
@include oIcons(); // include helper classes for all icons

To avoid including all icon helper classes, oIcons mixin also accepts a list of icons to include:

@include oIcons($opts: (
	'icons': ('arrow-down', 'audio') // include helper classes for the arrow-down and audio icons
));

Contributing

o-icons is some Sass mixins and helpers for using the fticons image set. To add a new icon you need to add it to the fticons set. There are instructions in the fticons README. When the icon is in fticons, run node ./scripts/build-icon-list.js to update o-icons Sass with the new icon automatically.
