Also note that the position and size of ruby text will vary across browsers/versions consider disabling browser defaults with a and sizing/positioning ruby text manually. Is explained in the W3C’s HTML5 specification, in the section on text-level semantics.

To achieve the same effect with font-feature-settings, use the “ruby” feature tag.Note the rt element that we’re styling, in the code sample above.
To enable it with the font-variant property or font-variant-east-asian subproperty, use the value ruby. The ruby notation forms feature is disabled by default. Some type foundries offer documentation about how features are organized.For now, we’ll skip the font-variant property because its “named” values (like styleset(sharp-serifs)) are mapped to numeric stylistic set indices by font-feature-value CSS definitions, which are not yet supported in any major browser. Note that fonts employ stylistic sets in completely arbitrary and custom ways.įor example, two different fonts may employ the same feature (like ss01) to replace totally different sets of glyphs or, a particular font may use ss01 and ss03 to replace sets of glyphs, but ignore ss02. The stylistic sets feature is disabled by default.To enable it with font-feature-settings, use the “ss#” feature tag, where “#” is any two-digit combination from 01–20. Furthermore, it cannot be disabled in Safari (Mac or iOS). Like ligatures (though not strictly a ligature feature), contextual alternates are commonly used to harmonize the shapes of glyphs with the surrounding context.The contextual alternates feature is enabled by default, which means it should work without you having to write any CSS - but it’s not enabled by default in Chrome. This feature, in specified situations, replaces default glyphs with alternate forms which provide better joining behavior. And some versions of Chrome and Firefox have trouble with ligatures that contain spaces. When enabled, this feature inserts the ligatures which the designer/manufacturer judges should be used in normal conditions.The ligatures feature is enabled by default, which means it should work without you having to write any CSS - but it’s not enabled by default in Chrome.įurthermore, it cannot be disabled in Safari (Mac or iOS). This feature replaces a sequence of glyphs with a single glyph, called a ligature, which is preferred for typographic purposes.
