## Syntax

```css
/* Keyword values */
font-variant-ligatures: normal;
font-variant-ligatures: none;
font-variant-ligatures: common-ligatures; /* <common-lig-values> */
font-variant-ligatures: no-common-ligatures; /* <common-lig-values> */
font-variant-ligatures: discretionary-ligatures; /* <discretionary-lig-values> */
font-variant-ligatures: no-discretionary-ligatures; /* <discretionary-lig-values> */
font-variant-ligatures: historical-ligatures; /* <historical-lig-values> */
font-variant-ligatures: no-historical-ligatures; /* <historical-lig-values> */
font-variant-ligatures: contextual; /* <contextual-alt-values> */
font-variant-ligatures: no-contextual; /* <contextual-alt-values> */

/* Global values */
font-variant-ligatures: inherit;
font-variant-ligatures: initial;
font-variant-ligatures: unset;

font-variant-ligatures取值为下列关键字之一。

Values

• normal
  • : 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。
• none
  • : 不使用任何连字，包括常规的形式

• \

  • : These values control the most common ligatures, like for fi, ffi, th or similar. They correspond to the OpenType values liga and clig. Two values are possible:
  • common-ligatures activating these ligatures. Note that the keyword normal activates these ligatures.
  • no-common-ligatures deactivating these ligatures.

• \

  • : These values control specific ligatures, specific to the font and defined by the type designer. They correspond to the OpenType values dlig. Two values are possible:
  • discretionary-ligatures activating these ligatures.
  • no-discretionary-ligatures deactivating the ligatures. Note that the keyword normal usually deactivates these ligatures.

• \

  • : 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 hlig. Two values are possible:
  • historical-ligatures activating these ligatures.
  • no-historical-ligatures deactivating the ligatures. Note that the keyword normal usually deactivates these ligatures.

• \

  • : 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 calt. Two values are possible:
  • contextual specifies that the contextual alternates are to be used. Note that the keyword normal usually activates these ligatures too.
  • no-contextual prevents their use.
