<h2 id="Sumário">Sumário</h2>

<p>A propriedade <strong><code>font-feature-settings</code></strong> do CSS te dá controle sobre tipografia avançada nas fontes do tipo OpenType.</p>

<div class="note"><strong>Nota:</strong> Sempre que possível, deve usar o {{cssxref("font-variant")}} propriedade abreviada ou uma propriedade extensa associada, {{cssxref("font-variant-ligatures")}}, {{cssxref("font-variant-caps")}}, {{cssxref("font-variant-east-asian")}}, {{cssxref("font-variant-alternates")}}, {{cssxref("font-variant-numeric")}} ou {{cssxref("font-variant-position")}}.<br>
<br>
Esta propriedade é um recurso de baixo nível projetado para lidar com casos especiais onde não existe outra maneira de habilitar ou acessar um recurso de fonte OpenType.<br>
<br>
Em particular, esta propriedade CSS não deve ser usada para habilitar small caps.</div>

<h2 id="Sintaxe">Sintaxe</h2>

<pre class="brush:css notranslate">/* Use the default settings */
font-feature-settings: normal;

/* Set values for OpenType feature tags */
font-feature-settings: "smcp";
font-feature-settings: "smcp" on;
font-feature-settings: "swsh" 2;
font-feature-settings: "smcp", "swsh" 2;

/* Global values */
font-feature-settings: inherit;
font-feature-settings: initial;
font-feature-settings: unset;
</pre>

<h3 id="Valores">Valores</h3>

<dl>
 <dt><code>normal</code></dt>
 <dd>Text is laid out using default settings.</dd>
 <dt><code>&lt;feature-tag-value&gt;</code></dt>
 <dd>Ao renderizar texto, a lista de características OpenType é passada para o mecanismo de layout de texto para ativar ou desativar recursos do tipo de letra. A tag é sempre uma {{cssxref("&lt;string&gt;")}} de 4 caracteres ASCII. Se possuir mais ou menos caracteres ou conter caracteres fora da faixa U+20 - U+7E, toda a propriedade é invalida.<br>
 O valor é um inteiro positivo. As duas palavras-chaves <code>on</code> e <code>off</code> são sinônimos de <code>1</code> e <code>0</code> respectivamente. Se nenhum valor é definido, o padrão é <code>1</code>. Para características OpenType não-booleanas (ex. <a href="http://www.microsoft.com/typography/otspec/features_pt.htm#salt">stylistic alternates</a>), o valor implica em um glifo particular para ser selecionado; para valores booleanos, é um interruptor.</dd>

<p>[1] From Gecko 2.0 (Firefox 4.0) to Gecko 14.0 (Firefox 14.0) included, Gecko supported an older syntax, slightly different from the modern one: <a href="http://hacks.mozilla.org/2010/11/firefox-4-font-feature-support/" title="http://hacks.mozilla.org/2010/11/firefox-4-font-feature-support/">OpenType Font Feature support in Firefox 4</a>.</p>

<p>[2] The <a href="http://mpeg.chiariglione.org/standards/mpeg-4/open-font-format/text-isoiec-cd-14496-22-3rd-edition">ISO/IEC CD 14496-22 3rd edition</a> suggests to use the <code>ssty</code> feature to provide glyph variants adjusted to be more suitable for use in scripts (for example primes used as superscripts). Starting with Firefox 29, this is done automatically by the <a href="/en-US/docs/Web/MathML">MathML</a> rendering engine. It also suggests applying the <code>dtls</code> feature to letters when positing mathematical accent over it, in order 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 always override via CSS the default values determined by the MathML rendering engine.</p>

<p>[3] Starting with Firefox 34, the version prefixed with <code>-moz-</code> is only kept for backward compatibility purpose. It is controlled by the <code>layout.css.prefixes.font-features</code>, defaulting to <code>true</code>. The prefixed property will be removed in the future.</p>
