HTML 5 <bdi> Tag

The HTML <bdi> tag is used on a span of text that is to be isolated from its surroundings for the purposes of bidirectional text formatting.

This can be useful when displaying right-to-left text (such as Arabic) inside left-to-right text (such as English) when the text-direction is unknown. The <bdi> element allows you to honor the correct directionality of text when this is unknown (such as in the case with user-generated content).

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.


* Note that the global dir attribute defaults to auto on this element (it never inherits from the parent element like with other elements).

Global Attributes

The following attributes are standard across all HTML 5 tags.

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Here are the standard HTML 5 event handler content attributes.

For a full explanation of these attributes, see HTML 5 event handler content attributes.
