<p><code>font-variant-ligatures</code>取值为下列关键字之一。</p>

<h3 id="Values">Values</h3>

<dl>
 <dt><code>normal</code></dt>
 <dd>默认值，表示在渲染时会使用常用的连字，连字的效果取决于字体，语言和脚本。</dd>
 <dt><code>none</code></dt>
 <dd>不使用任何连字，包括常规的形式</dd>
 <dt><em>&lt;common-lig-values&gt;</em></dt>
 <dd>These values control the most common ligatures, like for <code>fi</code>, <code>ffi</code>, <code>th</code> or similar. They correspond to the OpenType values <code>liga</code> and <code>clig</code>. Two values are possible:
 <ul>
  <li><code>common-ligatures</code> activating these ligatures. Note that the keyword <code>normal</code> activates these ligatures.</li>
  <li><code>no-common-ligatures</code> deactivating these ligatures.</li>
 </ul>
 </dd>
 <dt><em>&lt;discretionary-lig-values&gt;</em></dt>
 <dd>These values control specific ligatures, specific to the font and defined by the type designer. They correspond to the OpenType values <code>dlig</code>. Two values are possible:
 <ul>
  <li><code>discretionary-ligatures</code> activating these ligatures.</li>
  <li><code>no-discretionary-ligatures</code> deactivating the ligatures. Note that the keyword <code>normal</code> usually deactivates these ligatures.</li>
 </ul>
 </dd>
 <dt><em>&lt;historical-lig-values&gt;</em></dt>
 <dd>These values control the ligatures used historically, in old books, like the German tz digraph being displayed as ꜩ. They correspond to the OpenType values <code>hlig</code>. Two values are possible:
 <ul>
  <li><code>historical-ligatures</code> activating these ligatures.</li>
  <li><code>no-historical-ligatures</code> deactivating the ligatures. Note that the keyword <code>normal</code> usually deactivates these ligatures.</li>
 </ul>
 </dd>
 <dt><em>&lt;contextual-alt-values&gt;</em></dt>
 <dd>These values control whether letters adapt to their context—that is, whether they adapt to the surrounding letters. These values correspond to the OpenType values <code>calt</code>. Two values are possible:
 <ul>
  <li><code>contextual</code> specifies that the contextual alternates are to be used. Note that the keyword <code>normal</code> usually activates these ligatures too.</li>
  <li><code>no-contextual</code> prevents their use.</li>
 </ul>
