For example, cv01, cv02, cv03, etc swash( feature-value-name)Įnables display of swash glyphs (font specific, OpenType feature: swsh feature-index, cswh feature-index). For example, ss01, ss02, ss03, etc character-variant( feature-value-name #)Įnables display of specific character variants (font specific, OpenType feature: cv feature-index). styleset( feature-value-name #)Įnables display with stylistic sets (font specific, OpenType feature: ss feature-index). historical-formsĮnables display of historical forms (OpenType feature: hist). stylistic( feature-value-name)Įnables display of stylistic alternates (font specific, OpenType feature: salt feature-index). These are the possible values for the font-variant-alternates property. no-contextual Disables display of contextual alternates. This can be one of the following values: contextual Enables display of contextual alternates. Specifies whether contextual alternates are enabled or not (OpenType feature: hlig). no-historical-ligatures Disables display of historical ligatures.
This can be one of the following values: historical-ligatures Enables display of historical ligatures. Specifies whether historical ligatures (OpenType feature: hlig) are enabled or not. no-discretionary-ligatures Disables display of discretionary ligatures. Which ligatures are discretionary or optional is decided by the type designer, so authors will need to refer to the documentation of a given font to understand which ligatures are considered discretionary. This can be one of the following values: discretionary-ligatures Enables display of discretionary ligatures. Specifies whether discretionary ligatures (OpenType feature: dlig) are enabled or not. no-common-ligatures Disables display of common ligatures. For OpenType fonts, common ligatures are enabled by default. This can be one of the following values: common-ligatures Enables display of common ligatures. Specifies whether common ligatures (OpenType features: liga, clig) are enabled or not. They are grouped under common ligatures, discretionary ligatures, historical ligatures, and contextual alternates.
These are the possible values for the font-variant-ligatures property. none Sets font-variant-ligatures to none and resets all other font feature properties to their initial value. normal Resets all subproperties to their initial value. Normal | none | || || || || ordinal || slashed-zero || || || ruby || ] Possible ValuesĬSS3 supports font features that are included in the major font formats such as OpenType and Apple Advanced Typography (AAT).īelow are the values defined in CSS3 (including the OpenType feature tag/s where applicable). The font-variant property allows you to enable and/or control specific features as required. Some font features are applicable only to certain language scripts or specific languages, or in certain writing modes. Not all font features will necessarily be available to you all the time.
For example you can do things like, enable fancy stylistic capital letters (swash caps), have slashes through your zeros, choose between ranging (full-height) and non-ranging (old-style, or lower-case) digits, control of glyph substitution and sizing in East Asian text, and more. Most modern font technologies support a variety of font features which change the way the font looks in certain cases. So in CSS3 the font-variant property allows you to specify which font features to enable on a font and how they should work. In CSS3, while it still allows you to specify small caps, it has been expanded to be a shorthand property for the following new font variant subproperties: In CSS1 and CSS2, the font-variant property's sole purpose was to set text to small caps. These are the set of properties that provide control over stylistic font features. The font-variant property is a shorthand property for all font-variant subproperties.
