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 */
text-orientation: inherit;
text-orientation: initial;
text-orientation: unset;

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


Rotates the characters of horizontal scripts 90° clockwise. Lays out the characters of vertical scripts naturally. Default value.
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.
Causes characters to be laid out as they would be horizontally, but with the whole line rotated 90° clockwise.
An alias to sideways that is kept for compatibility purposes.
On SVG elements, this keyword leads to use the value of the deprecated SVG properties glyph-orientation-vertical and glyph-orientation-horizontal.

1. From version 38 until version 51 (exclusive): this feature is behind the layout.css.vertical-text.enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.

2. sideways-right has become an alias of sideways.
