Syntax

unicode-bidi: normal | embed | isolate | bidi-override | isolate-override | plaintext

Values

  • normalElement does not open an additional level of embedding. For inline elements, implicit reordering works across element boundaries.
  • embedElement opens an additional level of embedding. The value of the direction property specifies the embedding level. Reordering is implicit inside the element.
  • isolateThis keyword indicates that the element's container directionality should be calculated without considering the content of this element.
  • bidi-overrideSame as the embed value, except that, inside the element, reordering is strictly in sequence according to the direction property. This value overrides the implicit bidirectional algorithm.
  • isolate-overrideThis keyword applies the isolation behavior of the isolate keyword to the surrounding content and the override behavior of the bidi-override keyword to the inner content.
  • plaintextThis keyword makes the elements directionality calculated without considering its parent bidirectional state or the value of the direction property. The directionality is calculated using the P2 and P3 rules of the Unicode Bidirectional Algorithm.
  • inherit

Example

<p> A paragraph that does not use a bidirectional text display algorithm.  </p> 
<p class="test"> A paragraph that uses a bidirectional text display algorithm and the direction of the letter from right to left. </p>
.test {
   direction: rtl;
   unicode-bidi: bidi-override;
}
