<bdo>
Bidirectional override: forces a run of text to render in an explicit direction.
Baseline: Widely available · Inline text semantics
When to use it
Rarely — only when you must override the Unicode bidi algorithm deliberately.
When not to
For isolating unknown-direction text use bdi; for whole blocks use the dir attribute.
Key attributes
dir- ltr or rtl (required)
Example
this renders right-to-left
<p><bdo dir='rtl'>this renders right-to-left</bdo></p>
