The CSS `writing-mode` property specifies where in the available area text should begin and in which direction it should flow. It also specifies the position of the next line when a line break occurs. In Japanese vertical text, it can be difficult to read if new lines start on the right side. Therefore, it is better to use the term “writing-mode.” CSSのwriting-modeは、利用可能なエリアのどこから埋め始めて、どの方向に埋めていくかを指定します。また、改行がある場合の次の行の位置も指定します。日本語の縦書きで、新しい行を右側に作られると読みにくいです。そこで、writing modeという用語を使うのがベターでしょう。 2026年9月4日(金) 23:15 Yasuo Kida <kida@mac.com>: > > I strongly believe that the lack of a perfect, fully automatic transformation should not be used as a reason not to introduce switching between vertical and horizontal writing modes.
