These tests check whether user agents correctly apply the auto value of the dir attribute to improve handling of bidirectional text in languages such as Arabic, Hebrew, Persian, Thaana, Urdu, etc.
To see the test, click on the link in the left-most column. To see detailed results for a single test, click on a row and look just above the table. The detailed results show the date(s) the test result was recorded, and the version of the browser tested.
Any dependencies are shown in notes above the table, and notes below the table will usually provide any additional useful information, including an explanation of why a result was marked as 'partially successful'. Where the instructions tell you to look for red characters, these characters should be clearly discernable behind the black text of the test – ignore any anti-aliasing 'glow'.

| dir=auto, inline auto direction the-dir-attribute-046.html |
When dir='auto', the direction is set according to the first strong character of the text. dir=auto is applied to an inline element here, in various base direction contexts. | pass | pass | pass | pass | fail | fail |
| dir=auto, inline isolation the-dir-attribute-047.html |
dir='auto' on an inline element will directionally isolate its contents from a following number. | pass | pass | pass | pass | fail | fail |
| dir=auto, start with L the-dir-attribute-048.html |
When dir='auto', the direction is set according to the first strong character of the text. In this test, it is the Latin letter A, thus the direction must be resolved as LTR. | pass | pass | pass | pass | fail | fail |
