The font-variant-ligatures property is specified as one of the keyword values listed below.

Values

normal

This keyword leads to the activation of the usual ligatures and contextual forms needed for correct rendering. The ligatures and forms activated depend on the font, language and kind of script. This is the default value.

none

This keyword specifies that all ligatures and contextual forms are disabled, even common ones.

<common-lig-values>

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.

<discretionary-lig-values>

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.

<historical-lig-values>

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.

<contextual-alt-values>

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.

Formal syntax

normal | none | [ <common-lig-values> || <discretionary-lig-values> || <historical-lig-values> || <contextual-alt-values> ]
where 
<common-lig-values> = [ common-ligatures | no-common-ligatures ]
<discretionary-lig-values> = [ discretionary-ligatures | no-discretionary-ligatures ]
<historical-lig-values> = [ historical-ligatures | no-historical-ligatures ]
<contextual-alt-values> = [ contextual | no-contextual ]
