When i was a little kid, I was really scared of the dark. But then I came to understand, dark just means the absence of photons in the visible wavelength -- 400 to 700 nanometers. Then i thought, well, its really silly to be afraid of a lack of photons. Then i wasn't afraid of the dark anymore after that.

text-orientation

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.
