This property specifies the inline base direction or directionality of any bidi paragraph, embedding, isolate, or override established by the box. (See .) In addition, it informs the ordering of table column layout, the direction of horizontal overflow, and the default alignment of text within a line, and other layout effects that depend on the box’s inline base direction.

]]> Normally (i.e. when unicode-bidi is normal) an inline box is transparent to the unicode bidi algorithm; content is ordered as if the box’s boundaries were not there. Other values of the unicode-bidi property cause inline boxes to create scopes within the algorithm, and to override the intrinsic directionality of text.

]]> This property specifies the orientation of text within a line. Current values only have an effect in vertical typographic modes: the property has no effect on boxes in horizontal typographic modes.

]]> Some SVG user agents will need to process documents containing the obsolete SVG glyph-orientation-vertical property, which was defined to accept an auto keyword as well as <angle> and <integer> values representing multiples of 90°. While supporting this property is optional, UAs that do so must alias glyph-orientation-vertical as a shorthand of

]]> This property specifies the combination of multiple typographic character units into the space of a single typographic character unit. If the combined text is wider than 1em, the UA must fit the contents within 1em, see below. The resulting composition is treated as a single upright glyph for the purposes of layout and decoration. This property only has an effect in vertical writing modes.
