Html html tag

The <html> tag tells the browser that this is an HTML document.

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.
