Custom fonts
The application contains a set of built-in fonts, but you can easily include custom fonts. This topic describes how to include a locally stored custom font in your theme.
If you are new to theme development, see themes to get familiar with the basics.
To ensure the stability of your customizations and prevent upgrades from overwriting your customizations, do not change the default theme files. You must include custom fonts in the your theme's stylesheet.
Add font files to your local theme directory. For example,
app/design/frontend/<your_vendor_name>/<your_theme_name>/web/fonts.To add external fonts, add font references to the page configuration file as described in Include static resources (JavaScript, CSS, fonts).
If you build a theme using the UI library, declare the custom font by adding the
.lib-font-facemixin to theapp/design/frontend/<your_vendor_name>/<your_theme_name>/web/css/source/_typography.lessfile:Copied to your clipboard.lib-font-face(@family-name:'<custom_font_name>',@font-path: '@{baseDir}fonts/<path_to_font_file>',@font-weight: <font_weight>,@font-style: <font_style>,@font-display: <auto|block|fallback|optional|swap>);Where:
@{baseDir}stands for theapp/design/frontend/<you_vendor_name>/<your_theme_name>/webdirectory.<path_to_font_file>includes the font file name, but without the extension. For example,@font-path: '@{baseDir}fonts/Luma-Icons'for the font stored inweb/fonts/Luma-Icons.woff.
The mixin generates the CSS, which includes the font. The following example shows how to generate CSS for the Open Sans font in the Blank theme:
Copied to your clipboard@font-face {font-family: 'Open Sans';src: url('../fonts/opensans/light/opensans-300.eot');src: url('../fonts/opensans/light/opensans-300.eot?#iefix') format('embedded-opentype'), url('../fonts/opensans/light/opensans-300.woff2') format('woff2'), url('../fonts/opensans/light/opensans-300.woff') format('woff'), url('../fonts/opensans/light/opensans-300.ttf') format('truetype'), url('../fonts/opensans/light/opensans-300.svg#Open Sans') format('svg');font-weight: 300;font-style: normal;font-display: swap;}
@font-format and @font-type are optional but they are both related. If you need to specify a format, enclose it in single quotes. For example, @font-format: 'ttf' with @font-type: 'truetype' for TrueType Fonts. The available types are: "woff", "woff2", "ttf", "eot", "otf", and "svg"
Copied to your clipboard.lib-font-face(@family-name:'<custom_font_name>',@font-path: '@{baseDir}fonts/<path_to_font_file>',@font-format: '<ttf|woff|woff2|eot|otf|svg>',@font-weight: <font_weight>,@font-style: <font_style>,@font-display: <auto|block|fallback|optional|swap>,@font-type: <font_type>);
@font-display: swap is declared by default for Blank theme in app/design/frontend/Magento/blank/web/css/source/_typography.less.
Fallback web fonts that are used by default are located in lib/web/css/source/lib/variables/_typography.less.
For more information about font-face, refer to this article [Font-face][https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face].
<font> head type
A <font> node is added to HTML <head> type for layout in lib/internal/Magento/Framework/View/Layout/etc/head.xsd. All resources added with <font> node will be downloaded with preload html attribute.
Icon CSS
In addition to including custom fonts in your Blank theme, you also can include custom fonts for any icons in the Blank theme. The icon font files for the Blank theme are located in the lib/web/fonts/Blank-Theme-Icons directory. The lib/web/css/source/lib/variables/_typography.less file defines the font icon path and name for the icons and the web/css/source/_icons.less file uses these files to define the icon font face itself, which should be used in all CSS declarations.
The Unicode characters that correspond to the correct font glyphs for each icon are defined in the following lib/web/css/source/lib/variables/_icons.less file.
By calling the lib-icon-font mixin, you can apply the icon font and character variables throughout the theme LESS code.
For Example:
Copied to your clipboard.icon-calendar {.lib-icon-font(@icon-calendar,@_icon-font-size: 28px);}
See the UI library for an icon list and implementation.
To customize a font you import, consider using IcoMoon. To override Luma or Blank theme icon fonts, change the font path in the _theme.less file. For example:
Copied to your clipboard// Fonts@icons__font-path: '@{baseDir}fonts/Theme-Icons'; // Add you fonts in your-theme/web/fonts@icons__font-name: 'Theme-Icons';
With uploaded icons from IcoMoon, a "404 error woff2 file icon not found" may occur in the console. This means the woff2 file is missing from the IcoMoon package. You just need copy the woff file to woff2.
If your theme does not use the UI library, include the font in your theme's CSS files using the @font-face CSS rule.
