• Text attributes

The direction attribute affects the writing direction of the text in the block-level element, the direction of the column layout in the table, the direction of the element box filled with content horizontally, and the position of the last row in the alignment element at both ends.

Note: For intra-row elements, the direction attribute is applied only when the unicode-bidi attribute is set to embed or bidi-override.
