Some XHTML attributes are the same for all XHTML tags and go with them. There are three different kinds of XHTML attributes:
- Core Attributes
- Language Attributes
- Microsoft Proprietary Attributes
Core Attributes
The base, head, html, meta, param, script, style, and title elements can’t have the core attribute.
| Attribute | Value | Description |
|---|---|---|
| class | class_rule or style_rule | It specifies the element’s class. |
| id | id_name | It specifies the element’s unique id. |
| style | style_definition | It describes the definition of an inline style. |
| title | tooltip_text | It specifies the text that will be displayed in the mouse tip. |
Language Attributes
The lang attribute says what language the content inside is written in. It uses the ISO standard abbreviations for languages, like fr for French, en for English, etc. The language attribute is not allowed in the base, br, frame, frameset, hr, iframe, param, and script elements.
| Attribute | Value | Description |
|---|---|---|
| dir | ltr | rtl | The direction of the text is determined by it. |
| lang | language_code | To set the language code, use this. |
Microsoft Proprietary Attributes
There are some features that are unique to Microsoft that were added to Internet Explorer 4 and later.
| Attribute | Value | Description |
|---|---|---|
| accesskey | character | It is used to assign a keyboard shortcut to an element. |

| disabled | Boolean | The disabled attribute fades the element and prevents it from responding to user input. It has two possible values: true or false. |
| hidefocus | On or Off | This proprietary feature, introduced with Internet Explorer 5.5, hides the focus on the content of an element. It states that the tabindex attribute must be used to apply attention to the element. |
