CSS unicode-bidi Property
Topic: CSS3 Properties ReferencePrev|Next
Description
The unicode-bidi CSS property along with the direction property relates to the handling of bidirectional text in a document. For example, if a block of text contains both left-to-right and right-to-left text then the user-agent applies a complex algorithm defined by the Unicode standard to determining the proper directionality of text. The direction and unicode-bidi properties allow developers to control the embedding levels and overrides for this algorithm.
The following table summarizes the usages context and the version history of this property.
| Default value: | normal |
|---|---|
| Applies to: | All elements |
| Inherited: | No |
| Animatable: | No. See animatable properties. |
| Version: | CSS 2, 3 |
Note: This property should in most cases be used only by DTD designers. In particular, authors, web designers, and users shouldn't override it.

direction: rtl;
}Property Values
The following table describes the values of this property.
| Value | Description |
|---|---|
bidi-override |
For inline elements this creates an override. For block container elements this creates an override for inline-level descendants not within another block container element. This means that inside the element, reordering is strictly in sequence according to the direction property; the implicit part of the bidirectional algorithm is ignored. |
embed |
If the element is inline, this value opens an additional level of embedding with respect to the bidirectional algorithm. The direction of this embedding level is given by the direction property. |
normal |
This value doesn't offer an additional level of embedding with respect to the bidirectional algorithm. For inline elements, implicit reordering works across element boundaries. |
initial |
Sets this property to its default value. |
inherit |
If specified, the associated element takes the computed value of its parent element unicode-bidi property. |
Browser Compatibility
The unicode-bidi property is supported in all major modern browsers.
