CSS @font-face Rule


Specify a font named "myFirstFont", and specify the URL where it can be found:

@font-face {
  font-family: myFirstFont;
  src: url(sansation_light.woff);
Try it Yourself »

More "Try it Yourself" examples below.

Definition and Usage

With the @font-face rule, web designers do not have to use one of the "web-safe" fonts anymore.

In the @font-face rule you must first define a name for the font (e.g. myFirstFont), and then point to the font file.

Tip: Use lowercase letters for the font URL. Uppercase letters can give unexpected results in IE!

To use the font for an HTML element, refer to the name of the font (myFirstFont) through the font-family property:

div {
  font-family: myFirstFont;

Browser Support

The @font-face rule is supported in Internet Explorer, Firefox, Opera, Chrome, and Safari.

The numbers in the table specifies the first browser version that fully supports the font format.

Font format
TTF/OTF 4.0 9.0* 3.5 3.1 10.0
WOFF 5.0 9.0 3.6 5.1 11.1
WOFF2 36.0 Not supported 35.0* Not supported 26.0
SVG 4.0 Not supported Not supported 3.2 9.0
EOT Not supported 6.0 Not supported Not supported Not supported

*Edge and IE: The font format only works when set to be "installable".

*Firefox: Disabled by default, but can be enabled (need to set a flag to "true" to use WOFF2).


@font-face {

Font descriptor Values Description
font-family name Required. Defines the name of the font.
src URL Required. Defines the URL(s) where the font should be downloaded from
font-stretch normal
Optional. Defines how the font should be stretched. Default value is "normal"
font-style normal
Optional. Defines how the font should be styled. Default value is "normal"
font-weight normal
Optional. Defines the boldness of the font. Default value is "normal"
unicode-range unicode-range Optional. Defines the range of unicode characters the font supports. Default value is "U+0-10FFFF"

More Examples


You must add another @font-face rule containing descriptors for bold text:

@font-face {
  font-family: myFirstFont;
  src: url(sansation_bold.woff);
  font-weight: bold;
Try it Yourself »

The file "sansation_bold.woff" is another font file, that contains the bold characters for the Sansation font.

Browsers will use this whenever a piece of text with the font-family "myFirstFont" should render as bold.

This way you can have many @font-face rules for the same font.
