Sets the level of embedding with respect to the bidirectional algorithm.


{ unicode-bidi: sEmbedLevel }

Possible values


String that specifies one of the following values:


Default. Element does not open an additional level of embedding. For inline elements, implicit reordering works across element boundaries.


Same 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.


Element opens an additional level of embedding. The value of the direction property specifies the embedding level. Reordering is implicit inside the element.

The property has a default value of normal and is not inherited.


The unicode-bidi property is used with the direction property.

The Unicode bidirectional algorithm automatically reverses embedded character sequences according to their inherent direction. For example, the base direction of an English document is left-to-right. If parts of a paragraph within the document contain a language with a right-to-left reading order, the direction of that language displays correctly right-to-left. The browser applying the bidirectional algorithm correctly reverses the language direction.
