The <html> tag is supported in all major browsers.


Definition and Usage

The <html> tag represents the root of an HTML document.

The <html> tag is the container for all other HTML elements (except for the <!DOCTYPE> tag).


Differences Between HTML 4.01 and HTML5

HTML5 has added a new attribute: manifest.


Differences Between HTML and XHTML

The xmlns attribute is required in XHTML, but is invalid in HTML.

However, the HTML validator at http://w3.org does not complain when the xmlns attribute is missing in an XHTML document. This is because the namespace "xmlns=http://www.w3.org/1999/xhtml" is default, and will be added to the <html> tag even if you do not include it.


Attributes

New : New in HTML5.

Attribute Value Description
manifestNew URL Specifies the address of the document's cache manifest (for offline browsing)
xmlns http://www.w3.org/1999/xhtml Specifies the XML namespace attribute (If you need your content to conform to XHTML)


Global Attributes

The <html> tag also supports the Global Attributes in HTML.
