Adding fonts

Every project is unique. Logo, colors, fonts, etc. are what define the visual identity of your website. In this post, we'll cover adding fonts to a project.

Importing fonts into your project

Our documentation covers the necessary steps to add a font to your project, but here we'll cover the process in a bit more detail. To start, we need a font (or two). For this example, I'll use Source Sans Pro and Noto Serif which I've downloaded from Google Fonts. They are in the .ttf format (you may find some which are .otf, which will work in the same way), so you need to convert them to .woff and .woff2. Whatever approach you use is okay - we recommend the following tools:

Warning

Make sure you have the proper license for the fonts you are converting.

Fonts should go inside your theme's /assets/fonts folder. Copy the fonts you want to use there. You will also notice that this folder contains an index.js file, used to import fonts into your project. Here's an example of how I imported my fonts:

// SourceSansPro WOFF
import './SourceSansPro-Bold.woff';
import './SourceSansPro-BoldItalic.woff';
import './SourceSansPro-Italic.woff';
import './SourceSansPro-Regular.woff';
import './SourceSansPro-Light.woff';
import './SourceSansPro-LightItalic.woff';

// SourceSansPro WOFF2
import './SourceSansPro-Bold.woff2';
import './SourceSansPro-BoldItalic.woff2';
import './SourceSansPro-Italic.woff2';
import './SourceSansPro-Regular.woff2';
import './SourceSansPro-Light.woff2';
import './SourceSansPro-LightItalic.woff2';

// NotoSerif WOFF
import './NotoSerif-Bold.woff';
import './NotoSerif-BoldItalic.woff';
import './NotoSerif-Italic.woff';
import './NotoSerif-Regular.woff';

// NotoSerif WOFF2
import './NotoSerif-Bold.woff2';
import './NotoSerif-BoldItalic.woff2';
import './NotoSerif-Italic.woff2';
import './NotoSerif-Regular.woff2';
Tip

If you don't need to support IE11, don't include .woff files. This will save you some bandwidth.

To add these fonts as your base font and secondary font, go to the global manifest located in /src/Blocks and add the following inside globalVariables:

"globalVariables": {
// ...
"baseFont": "SourceSansPro",
"secondaryFont": "NotoSerif",
// ...
}

Next, you can create a new file called _typography.scss inside your /assets/styles/parts/utils/ folder and add the following:

@include font-face(global-settings(baseFont), 'SourceSansPro-Light', 300);
@include font-face(global-settings(baseFont), 'SourceSansPro-LightItalic', 300, italic);
@include font-face(global-settings(baseFont), 'SourceSansPro-Regular', 400);
@include font-face(global-settings(baseFont), 'SourceSansPro-Italic', 400, italic);
@include font-face(global-settings(baseFont), 'SourceSansPro-Bold', 700);
@include font-face(global-settings(baseFont), 'SourceSansPro-BoldItalic', 700, italic);

@include font-face(global-settings(secondaryFont), 'NotoSerif-Bold', 700);
@include font-face(global-settings(secondaryFont), 'NotoSerif-BoldItalic', 700, italic);
@include font-face(global-settings(secondaryFont), 'NotoSerif-Italic', 400, italic);
@include font-face(global-settings(secondaryFont), 'NotoSerif-Regular', 400);

If you would like to know more about the font-face mixin, you can take a look at our Sass documentation.

Because this is a new file, we have to include it. You can do that inside /assets/styles/parts/_shared.scss file:

// Project specific.
@import 'utils/shared-variables';
@import 'utils/typography';

Run npm start to rebuild your public folder and assets. If you did everything correctly, your build should pass and you will see your fonts inside the public folder.

Using only one font in a block

There are multiple ways of using fonts in a block. The simplest use case is if you have only one font you want to use for that specific block. In this case, we want the Heading block to only use Noto Serif.

To make our secondary font available for use, we need to first define it as a CSS variable. We can do that in /assets/styles/parts/utils/_shared-variables.scss. The base font is already defined there, so all we need to do is add our secondary font definition below it.

To make things a bit more consistent, we may also want to rename --global-font-family CSS variable to --base-font-family. Just don't forget to search/replace this new variable name across your project! Please note that the fallbacks for the fonts can be anything, this is just an example. Once we're done, it should look like this:

	--base-font-family: var(--global-base-font), -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica,
Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol';

--secondary-font-family: var(--global-secondary-font), -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica,
Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol';

After defining the --secondary-font-family CSS variable, we can go to /src/Blocks/components/heading/heading-style.scss and add the following rule to the .heading class:

	font-family: var(--secondary-font-family);

And that's it! The Heading block will now use the Noto Serif font.

Adding a font picker

In some cases, you may want to give users the option to choose between fonts that they want to use in their block. For this example, we'll use the paragraph block where we want users to have both Source Sans Pro and Noto Serif available.

First step is to add a new attribute, options and CSS variable values in /src/Blocks/components/paragraph/manifest.json:

// ...
"attributes": {
// ...
"paragraphFontFamily": {
"type": "string",
"default": "base"
}
},
"options": {
// ...
"paragraphFontFamily": [
{
"label": "SourceSansPro",
"value": "base"
},
{
"label": "NotoSerif",
"value": "secondary"
}
],
// ...
}

After defining the new attribute and options for the font family, we now have to add a variable to manifest.json. We can add it to the variables object. This approach is slightly different from the one explained in the Modifying blocks blog post. Here we can use %value% wildcard to dynamically add the selected value to our CSS variable.

"paragraphFontFamily": [
{
"variable": {
"paragraph-font-family": "var(--%value%-font-family)"
}
}
]

The next step is to go to /src/Blocks/components/paragraph/components/paragraph-options.js and add a control for the new font family option. The first thing we can add is a new attribute that will allow us to toggle showing the Paragraph font family option on other blocks which are using the Paragraph component. There might be a case where we want only one font family, so this option may come in handy in some other blocks.

const {
setAttributes,
//...
showParagraphFontFamily = true,
} = attributes;

After that, we need to fetch either the saved attribute value or get the default one from the manifest. We can do that with the checkAttr helper, adding it just below paragraphColor and paragraphSize.

	const paragraphFontFamily = checkAttr('paragraphFontFamily', attributes, manifest);

Now we have to add an actual control to the options panel which will allow us to choose between fonts.

	return (
// ...
{showParagraphFontFamily &&
<CustomSelect
label={<IconLabel icon={icons.fontFamily} label={__('Font Family', 'eightshift-theme')} />}
value={paragraphFontFamily}
options={getOption('paragraphFontFamily', attributes, manifest)}
onChange={(value) => setAttributes({ [getAttrKey('paragraphFontFamily', attributes, manifest)]: value })}
isClearable={false}
isSearchable={false}
simpleValue
/>
}
// ...
);

The control for selecting a font should now be available under Paragraph options. Saving the choice now works, but the font stays the same both in the editor and on the frontend.

Font Picker

The final step we need to make this work is to add a CSS rule that consumes our variable to /src/Blocks/components/paragraph/paragraph-style.scss:

.paragraph {
// ...
font-family: var(--paragraph-font-family, var(--base-font-family));
// ...
}

After adding this single line of CSS code, your new option for selecting fonts will now be fully functional.

Closing thoughts

Adding fonts to a project is something you will usually only do when setting up a new project and then forget about it. As you could see in this blog post, this isn't a complicated process, but it has a specific set of steps that have to be taken in order for custom fonts to work in your project.

Of course, there are other ways to include fonts in your project, but the described process is what we recommend and use. This is the (Eightshift) Way.
