Revision 1132361 of @font-face

<h2 id="Summary">Summary</h2>

<p>The <strong><code>@font-face</code></strong> <a href="/en-US/docs/CSS">CSS</a> <a href="/en-US/docs/CSS/At-rule">at-rule</a> allows authors to specify online fonts to display text on their web pages. By allowing authors to provide their own fonts, <code>@font-face</code> eliminates the need to depend on the limited number of fonts users have installed on their computers. The <code>@font-face</code> at-rule may be used not only at the top level of a CSS, but also inside any <a href="/en-US/docs/CSS/At-rule#Conditional_Group_Rules">CSS conditional-group at-rule</a>.</p>

<h2 id="Examples">Examples</h2>

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

<p><a href="https://mdn.mozillademos.org/files/7775/webfont-sample.html">View the live example</a></p>

<pre class="brush: html">
&lt;html&gt;
&lt;head&gt;
  &lt;title&gt;Web Font Sample&lt;/title&gt;
  &lt;style type="text/css" media="screen, print"&gt;
    @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 }
  &lt;/style&gt;
&lt;/head&gt;
&lt;body&gt;
  This is Bitstream Vera Serif Bold.
&lt;/body&gt;
&lt;/html&gt;
</pre>

<p>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:</p>

<pre class="brush: css">
@font-face {
  font-family: MyHelvetica;
  src: local("Helvetica Neue Bold"),
       local("HelveticaNeue-Bold"),
       url(MgOpenModernaBold.ttf);
  font-weight: bold;
}
</pre>

<h2 id="Notes">Notes</h2>

<ul>
 <li>Web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless <a href="/en-US/docs/HTTP_access_control">HTTP access controls</a> are used to relax this restriction.</li>
 <li>Because there are no defined MIME types for TrueType, OpenType, and Web Open File Format (WOFF) fonts, the MIME type of the file specified is not considered.</li>
 <li>@font-face cannot be declared within a CSS selector.&nbsp;For example, the following will not work:</li>
</ul>

<ul>
 <li>
  <pre class="brush: css">
.className { 
   @font-face { 
&nbsp;  font-family: MyHelvetica; 
&nbsp;  src: local("Helvetica Neue Bold"), 
&nbsp;  local("HelveticaNeue-Bold"), 
&nbsp;  url(MgOpenModernaBold.ttf); 
&nbsp;  font-weight: bold; 
&nbsp;  } 
}</pre>
 </li>
</ul>

<p>[1] WOFF2 supports from Gecko 35 to Gecko 38 included is only activated by default on Aurora and Nightly versions. To use it on Beta and Release versions, the user needs to set the <code>gfx.downloadable_fonts.woff2.enabled</code> preference to <code>true</code>.</p>

<p>[2] Support for SVG Fonts was dropped in favor of allowing SVG glyphs within OpenType font packages.</p>

<p>[3] For Gecko there was {{Bug("119490")}} filed for implementing SVG Fonts, though as SVG Fonts got superseded by SVG glyphs within OpenType font packages, the bug got closed.</p>

<h3 id="Notes_2">Notes</h3>

<ul>
 <li>Support of the Embedded OpenType font format is not included in the compatibility table because it is a proprietary feature. Prior to IE 9.0, IE supported only this format.</li>
 <li>TrueType and OpenType are not included because they are superseded by WOFF.</li>
 <li>The same origin policy is not implemented in WebKit based browsers like Safari and Mobile Safari. This was also true for Blink based browsers, until September, 2014 - Chrome 37 and Opera 24.</li>
</ul>
