CSS - text-combine-upright Property

The text-combine-upright property specifies the combination of multiple typographic character units into the space of a single typographic character unit. This property basically can be used for vertical writing such as in Japanese, chinese languages.

This property only has an effect in vertical writing modes. We can use text-combine-upright in conjunction with the writing-mode property to specify how multiple characters fit into a single space.

Possible Values

  • none: There is no special processing of the text.

  • all: Attempts to typeset all consecutive characters within the box horizontally. This makes sure that text take up the space of a single character within the vertical line of the box.

  • end: Aligned to right if the direction is ltr and left if the direction is rtl.

  • digits<integer>: As of now not supported by any browsers.

Applies to

All the HTML elements except table row groups, rows, column groups, and columns.

DOM Syntax

object.style.textCombineUpright = "all";
