font-feature-settings

The font-feature-settings CSS property controls advanced typographic features in OpenType fonts.

Values: This property is specified as either the keyword normal or as a comma-separated list of <feature-tag-value> values. When rendering text, the list of OpenType <feature-tag-value> values are passed to the text layout engine to enable or disable font features.

Values: normal Indicates that text is laid out using default font settings. This is the default value. <feature-tag-value> Represents a space-separated tuple consisting of a tag name and an optional value. Tag name The tag name is always a <string> of four ASCII characters. If the tag name has more or fewer characters or if it contains characters outside the U+20 – U+7E code point range, the descriptor is invalid. Optional value The optional value can be a positive integer or the keyword on or off. The keywords on and off are synonyms for the values 1 and 0, respectively. If no value is set, the default is 1. For non-boolean OpenType features (e.g., stylistic alternates), the value implies a particular glyph to be selected; for boolean features, the value turns the feature on or off.

Syntax example: font-feature-settings: normal;
