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.
Summary
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.
