Vertical writing mode
Also called tategaki, vertical typesetting, writing-mode
This entry has not been translated yet and is shown in English.
Setting text in columns running top to bottom, columns ordered right to left — the traditional mode for Japanese and Chinese, and current in books, newspapers and signage. CSS supports it via writing-mode: vertical-rl, with text-orientation governing whether Latin runs rotate or stand upright, and tate-chu-yoko setting short numbers horizontally within the column.
In practice
Not a rotation of the horizontal setting. Punctuation moves, brackets change glyph, and every logical property — inline-size, margin-block, padding-inline — starts earning its keep over width and margin-top.
