HTML 5 <bdo> Tag

The HTML <bdo> tag is used for overriding the text direction.

This can be useful when displaying right-to-left written text (such as Hebrew, Arabic, and other languages/scripts that are written from right to left) within left-to-right text (such as English) or vice versa.

Attributes

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.

AttributeDescription
dir** Although this element has no local attributes, you must use the dir global attribute. The dir attribute specifies the direction of the text:
  • ltr: Left to right
  • rtl: Right to left

This attribute must have the value ltr to specify a left-to-right override and with the value rtl to specify a right-to-left override.

Global Attributes

The following attributes are standard across all HTML 5 tags (although the tabindex attribute does not apply to dialog elements).

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.

For a full list of event handlers, see HTML 5 event handler content attributes.
