writing-mode

The writing-mode CSS property sets whether lines of text are laid out horizontally or vertically, as well as the direction in which text flows.

The writing-mode property sets whether lines of text are laid out horizontally or vertically. It specifies the block flow direction, which is the direction in which block-level containers are stacked, and the direction in which inline-level content flows within a block container. Thus, it also determines the ordering of block-level content.

The flow direction in horizontal scripts is also affected by the directionality of that script, either left-to-right (ltr, like English and most other languages) or right-to-left (rtl, like Hebrew or Arabic).

Syntax example: writing-mode: horizontal-tb;
