This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The text-orientation CSS property defines the orientation of the text characters in a line. This property only has an effect in vertical mode, that is, when writing-mode is not horizontal-tb. It is useful for controlling the display of languages that use vertical script, and also for making vertical table headers.

/* Keyword values */
text-orientation: mixed;
text-orientation: upright;
text-orientation: sideways-right;
text-orientation: sideways;
text-orientation: use-glyph-orientation;

/* Global values */

Syntax

The text-orientation property is specified as a single keyword from the list below.

Values

mixed
Rotates the characters of horizontal scripts 90°. Lays out the characters of vertical scripts naturally. Default value.
upright
Lays out the characters of horizontal scripts naturally (upright), as well as the glyphs for vertical scripts. Note that this keyword causes all characters to be considered as left-to-right: the used value of direction is forced to be ltr.
sideways
Causes characters to be laid out as if they were laid out horizontally, but with the whole line rotated 90° to the right if writing-mode is vertical-rl, or to the left if it is vertical-lr.
sideways-right
An alias to sideways that is kept for compatibility purposes.
use-glyph-orientation
On SVG elements, this keyword leads to use the value of the deprecated SVG properties glyph-orientation-vertical and glyph-orientation-horizontal.

Formal syntax
