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 in a line. This property only has an effect in vertical mode, that is when writing-mode is not horizontal-tb. It is useful to control the display of writing in languages using vertical script, but also to deal with vertical table headers.

This keyword leads to have characters for horizontal-only scripts being turned 90°, while the glyphs for vertical scripts are laid out naturally.
This keyword leads to have characters for horizontal-only scripts to be laid out naturally (upright), as well as the glyphs for vertical scripts. Note that this keyword lead all characters to be considered as ltr: the used value of direction is ltr, whatever the user could try to set it to.
This keyword leads to have characters laid out like 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.
An alias to sideways that is kept for compatibility purpose.
On SVG elements, this keyword leads to use the value of the deprecated SVG properties glyph-orientation-vertical and glyph-orientation-horizontal.
