@font-feature-values
規則の基本的な構文は下記のようになります。
@font-feature-values <family-name># { <declaration-rule-list> }
<family-name>
は、フォントファミリーの名称です。カンマ(,
)で区切って複数指定することも可能です。
<declaration-rule-list>
は下記ような記述になります。
@stylistic
font-variant-alternates
プロパティの stylistic()
関数から参照する特性値名を指定します。
@font-feature-values foo {

}
@historical-forms
font-variant-alternates
