Usage
Check out how to include Origami components in your project to get started with o-fonts
.
Recommended Fonts
Origami components use a limited set of recommended font faces which vary per brand. We recommend Sass users include only these recommended fonts and carefully consider performance implications before including another font. However a wider selection of fonts are included by default so they are available to Build Service users. Sass users may choose to include only recommended fonts, or any of the available fonts.
Core Brand Recommended Fonts
| Weight | FinancierDisplayWeb | MetricWeb | |----------|:-------------------:|:---------:| | thin | | | | light | | | | regular | | ✓ | | medium | ✓ | | | semibold | | ✓ | | bold | ✓ | | | black | | |
- ✓: normal style available
- i: italic style available (if not, faux-italic will be displayed)
Internal Brand Recommended Fonts
| Weight | MetricWeb | |----------|:---------:| | thin | | | light | | | regular | ✓ | | medium | | | semibold | ✓ | | bold | | | black | |
- ✓: normal style available
- i: italic style available (if not, faux-italic will be displayed)
Whitelabel Brand Recommended Fonts
(None). Origami components make no font assumptions for whitelabel brands and default to a system font.
Fonts Included By Default
A selection wider than recommended fonts are included by default so they are available to Build Service users. Font faces included by default, if using the Origami Build Service or including default fonts with SASS, depend on your products chosen brand:
| Brand | Fonts included by default (all weights and styles available) | |-------------|--------------------------------------------------------------------------------------| | core | FinancierDisplayWeb, MetricWeb | | internal | MetricWeb | | whitelabel | (none) |
All Available Fonts
Any of the below fonts may be included with o-fonts
using SASS, this is useful for brands such as specialist titles who may use additional fonts. Build Service users are limited to fonts included by default.
| Weight | FinancierDisplayWeb | FinancierTextWeb | MetricWeb | |----------|:-------------------:|:-------------------:|:---------:| | thin | | | ✓ | | light | ✓ i | | ✓ i | | regular | ✓ i | ✓ i | ✓ i | | medium | ✓ i | ✓ | ✓ | | semibold | ✓ i | | ✓ | | bold | ✓ | ✓ | ✓ i | | black | ✓ | ✓ | ✓ |
- ✓: normal style available
- i: italic style available (if not, faux-italic will be displayed)
Sass
Include Default Fonts
To include all fonts for your brand, call oFonts
.
@import '@financial-times/o-fonts/main';
@include oFonts();
To improve site performance, Origami components use a more limited set of font faces. To included only the recommended set of font faces, set recommended: true
in the options $opts
map.
@import '@financial-times/o-fonts/main';
@include oFonts($opts: ('recommended': true));
You may also include specific fonts granularly using an options $opts
map. The map has a key for each font metric
, financier-display
, or financier-text
, which accepts a list of weight and styles to include.
For example to include recommended fonts used by Origami components and an extra font, MetricWeb
in a medium weight, and regular FinancierDisplayWeb
:
@include oFonts($opts: (
'recommended': true,
'metric': (
('weight': 'medium', 'style': 'normal')
),
'financier-display': (
('weight': 'regular', 'style': 'normal')
)
));
Note: If your project has multiple Sass entry points call oFontsVariantsIncluded
with the same options as oFonts
, to tell o-fonts
which font faces have been output.
Font Loading
By default font-display is set to swap
. In supporting browsers a system font is shown until fonts are loaded. To update your font loading method set $o-fonts-display
at the top of your Sass, before including any other component.
// Customise font loading.
$o-fonts-display: 'optional';
@import '@financial-times/o-fonts/main';
@include oFonts();
Use a custom font family
To register a custom font and supported variants, use the mixin oFontsDefineCustomFont
.
In this example we register a custom font "MyFont" with sans fallback MyFont, sans
. We configure this font to allow two variants (a normal style of either bold or regular weight). In the mixin content we include the @font-face
declaration to load these fonts from our own source.
@include oFontsDefineCustomFont('MyFont, sans', (
(weight: regular, style: normal),
(weight: bold, style: normal)
)) {
@font-face {
src: url('MyFont-Thin.woff2') format('woff2'), url('MyFont-Thin.woff') format('woff');
font-family: MyFont;
font-weight: 100;
font-style: normal;
}
@font-face {
src: url('MyFont-Bold.woff2') format('woff2'), url('MyFont-Bold.woff') format('woff');
font-family: MyFont;
font-weight: 700;
font-style: normal;
}
}
Get a font family for a font name
To get a font-family
with web safe fallbacks for a font, use the oFontsGetFontFamilyWithFallbacks
function.
$family: oFontsGetFontFamilyWithFallbacks(FinancierDisplayWeb); // FinancierDisplayWeb, sans-serif
Get a font name from a font family
To get a font without fallbacks, use oFontsGetFontFamilyWithoutFallbacks
:
$font: oFontsGetFontFamilyWithoutFallbacks('FinancierDisplayWeb, sans-serif'); // FinancierDisplayWeb
Check a font of weight or style exists
To check if a font supports a weight/style use oFontsVariantExists
.
$allowed: oFontsVariantExists('MetricWeb', 'bold', 'normal'); // true
$allowed: oFontsVariantExists('MetricWeb', 'black', 'italic'); // false
Check a font of weight or style has been included
To check if a font weight/style has been output in your project use oFontsVariantIncluded
.
// including fonts in project
@include oFonts($opts: (
'metric': (
('weight': 'medium', 'style': 'normal')
),
));
$included: oFontsVariantIncluded('MetricWeb', 'medium', 'normal'); // true
$included: oFontsVariantIncluded('MetricWeb', 'bold', 'normal'); // false
Note: If your project has multiple Sass entry points call oFontsVariantsIncluded
with the same options as oFonts
, to tell o-fonts
which font faces have been output.
Contributing
Add a new font or font variant
Note: font files are contained in a separate, private repository (o-fonts-assets).
Open
src/scss/_variables.scss
and update the$o-fonts-build-service-path
variable to the release of o-fonts-assets which includes your new font.Add the font family name (if it's an entirely new family) and the variant styles to the private
$_o-fonts-families
map.If adding an entirely new font, add a new option to the
oFonts
mixin. To include the new font by default or with recommended fonts (see$_o-fonts-default
and$_o-fonts-recommended
).Finally, update the demos (see
origami.json
).
