Reading direction

Indicates the reading direction of the document or a passage of text via the dir attribute, dir="ltr", for example. The two recognised values are

• ltr (left to right) indicates a reading direction from left to right;
• rtl (right to left) indicates a reading direction from right to left.

Note: if there is no indication of reading direction via the dir attribute on the html, body element, or one of the parents of the text being analysed, the default reading direction is left to right (value ltr).
