text-combine-upright
The text-combine-upright
CSS property sets the combination of characters into the space of a single character. If the combined text is wider than 1em, the user agent must fit the contents within 1em. The resulting composition is treated as a single upright glyph for layout and decoration. This property only has an effect in vertical writing modes.
This is used to produce an effect that is known as tate-chū-yoko 縦中横
in Japanese, or as 橫向文字
in Chinese.
