BDI stands for Bi-Directional Isolation. This element is used to perform bidirectional text isolation i.e. text which may be formatted to execute in the opposite direction like left-to-right context or right-to-left context.
This tag is applicable for bidirectional languages such as Arabic and used inline with left-to-right languages.

<bdi> element is a new tag found in HTML5. Working of both <bdi> and older <bdo> tag is identical with only one difference i.e. <bdi> tag isolates the content from its surrounding content whereas <bdo> tag reverse the direction only.
Sometimes <bdo> tag may cause some unexpected rendering errors. This is the main reason why <bdi> is used.
