Web/CSS/@font-face

From Get docs


The @font-face CSS at-rule specifies a custom font with which to display text; the font can be loaded from either a remote server or a locally-installed font on the user's own computer.

Syntax

@font-face {
  font-family: "Open Sans";
  src: url("/fonts/OpenSans-Regular-webfont.woff2") format("woff2"),
       url("/fonts/OpenSans-Regular-webfont.woff") format("woff");
}

Descriptors

font-display
Determines how a font face is displayed based on whether and when it is downloaded and ready to use.
font-family
Specifies a name that will be used as the font face value for font properties.
font-stretch
A font-stretch value. Since Firefox 61 (and in other modern browsers) this also accepts two values to specify a range that is supported by a font-face, for example font-stretch: 50% 200%;
font-style
A font-style value. Since Firefox 61 (and in other modern browsers) this also accepts two values to specify a range that is supported by a font-face, for example font-style: oblique 20deg 50deg;
font-weight
A font-weight value. Since Firefox 61 (and in other modern browsers) this also accepts two values to specify a range that is supported by a font-face, for example font-weight: 100 400;
font-variant
A font-variant value.
font-feature-settings
Allows control over advanced typographic features in OpenType fonts.
font-variation-settings
Allows low-level control over OpenType or TrueType font variations, by specifying the four letter axis names of the features to vary, along with their variation values.
src

Specifies the resource containing the font data. This can be a URL to a remote font file location or the name of a font on the user's computer.

To provide the browser with a hint as to what format a font resource is — so it can select a suitable one — it is possible to include a format type inside a format() function:

src: url(ideal-sans-serif.woff) format("woff"),
     url(basic-sans-serif.ttf) format("truetype");

The available types are: "woff", "woff2", "truetype", "opentype", "embedded-opentype", and "svg".

unicode-range
The range of Unicode code points to be used from the font.

Description

If the local() function is provided, specifying a font name to look for on the user's computer, and the user agent finds a match, that local font is used. Otherwise, the font resource specified using the url() function is downloaded and used.

By allowing authors to provide their own fonts, @font-face makes it possible to design content without being limited to the so-called "web-safe" fonts (that is, the fonts which are so common that they're considered to be universally available). The ability to specify the name of a locally-installed font to look for and use makes it possible to customize the font beyond the basics while making it possible to do so without relying on an Internet connection.

It's common to use both url() and local() together, so that the user's installed copy of the font is used if available, falling back to downloading a copy of the font if it's not found on the user's device.

The @font-face at-rule may be used not only at the top level of a CSS, but also inside any CSS conditional-group at-rule.

Font MIME Types

Format MIME type
TrueType font/ttf
OpenType font/otf
Web Open Font Format font/woff
Web Open Font Format 2 font/woff2

Notes

  • Web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction.
  • @font-face cannot be declared within a CSS selector. For example, the following will not work:

    .className { 
      @font-face { 
        font-family: MyHelvetica; 
        src: local("Helvetica Neue Bold"),
             local("HelveticaNeue-Bold"),
             url(MgOpenModernaBold.ttf);
        font-weight: bold; 
      } 
    }

Formal syntax

@font-face {
  [ font-family: <family-name>; ] ||
  [ src: <src>; ] ||
  [ unicode-range: <unicode-range>; ] ||
  [ font-variant: <font-variant>; ] ||
  [ font-feature-settings: <font-feature-settings>; ] ||
  [ font-variation-settings: <font-variation-settings>; ] ||
  [ font-stretch: <font-stretch>; ] ||
  [ font-weight: <font-weight>; ] ||
  [ font-style: <font-style>; ]
}where <family-name> = <string> | <custom-ident>+

Examples

Specifying a downloadable font

This example simply specifies a downloadable font to use, applying it to the entire body of the document:

<html>
<head>
  <title>Web Font Sample</title>
  <style type="text/css" media="screen, print">
    @font-face {
      font-family: "Bitstream Vera Serif Bold";
      src: url("https://mdn.mozillademos.org/files/2468/VeraSeBd.ttf");
    }
    
    body { font-family: "Bitstream Vera Serif Bold", serif }
  </style>
</head>
<body>
  This is Bitstream Vera Serif Bold.
</body>
</html>

The output of this example code looks like so:

Specifying local font alternatives

In this example, the user's local copy of "Helvetica Neue Bold" is used; if the user does not have that font installed (two different names are tried), then the downloadable font named "MgOpenModernaBold.ttf" is used instead:

@font-face {
  font-family: MyHelvetica;
  src: local("Helvetica Neue Bold"),
       local("HelveticaNeue-Bold"),
       url(MgOpenModernaBold.ttf);
  font-weight: bold;
}

Notes' The ISO/IEC CD 14496-22 3rd edition suggests using the ssty feature to provide glyph variants more suitable for use in scripts (for example primes used as superscripts). Starting with Firefox 29, this is done automatically by the MathML rendering engine. The ISO/IEC CD 14496-22 3rd edition also suggests applying the dtls feature to letters when placing mathematical accents to get dotless forms (for example dotless i, j with a hat). Starting with Firefox 35, this is done automatically by the MathML rendering engine. You can override the default values determined by the MathML rendering engine with CSS. Full support 15
