<bdo>: The Bidirectional Text Override element - HTML: HyperText Markup Language 编辑

The HTML Bidirectional Text Override element (<bdo>) overrides the current directionality of text, so that the text within is rendered in a different direction.

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

The text's characters are drawn from the starting point in the given direction; the individual characters' orientation is not affected (so characters don't get drawn backward, for example).

Notes

The HTML 4 specification did not specify events for this element; they were added in XHTML. This is most likely an oversight.
