HTML5, bdi

To run the test, or to see detailed, per character, results, click on the link in the left-most column. To see detailed results click on a row and look just above the table.

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'.

Key: pass fail partially successful

These tests check whether browsers correctly handle the bdi element, to improve handling of bidirectional text in languages such as Arabic, Hebrew, Persian, Thaana, Urdu, etc.

Basic tests

These basic tests check that the bdi element directionally isolates the text inside from that outside, and that it applies first-strong rules to determine the base direction of the text inside it.

Other tests

These other tests check for edge cases.
