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 examplefont-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 examplefont-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 examplefont-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>
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; }
