    <bdi> Redirect 1


    The HTML <bdi> Element (or Bi-Directional Isolation Element) isolates a span of text that might be formatted in a different direction from other text outside it.

    This element is useful when embedding text with an unknown directionality, from a database for example, inside text with a fixed directionality.

    Though the same visual effect can be achieved using the CSS rule unicode-bidi: isolate on a <span> or another text-formatting element, the semantic meaning is only conveyed by the <bdi> element. Especially, browsers are allowed to ignore CSS styling. In such a case, the text would still be correctly displayed using the HTML element, but will become garbage when using the CSS styling to convey semantic.


    Like all other HTML elements, this element has the global attributes, with a slight semantic difference: the dir attribute is not inherited. If not set, its default value is the auto which let the browser decide the direction based on the element's content.
