HTML <bdi> Tag

The <bdi> tag (bidirectional isolation) is one of the HTML5 elements. It is used to isolate bidirectional text (when a language with right-to-left directionality, such as Arabic or Hebrew, is used in line with left-to-right languages). Note, that the <bdi> tag does not physically turn the text, it only tells the browser that the text should be read in the opposite direction.

The <bdi> tag comes in pairs; the content is written between the opening (<bdi>) and the closing (</bdi>) tags.
