Question

What do you mean by orientation of text?
​

Answer 1

Answer:

Basically, it rotates either the line by 90° clockwise to help control how vertical languages are displayed — much like the way text-combine-upright rotates groups of characters within a line of text in a vertical script, but for full lines of text. ..

Answer 2

Answer:

The text-orientation CSS property sets the orientation of the text characters in a line. It only affects text in vertical mode (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.
