Definition and UsageThe <html> tag tells the browser that this is an HTML document.
The html element is the outermost element in HTML and XHTML documents. The html element is also known as the root element.
The <html> tag is supported in all major browsers.
Differences Between HTML and XHTMLThe xmlns attribute is required in XHTML but it is invalid in HTML.
However, the HTML validator at 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.
Tips and NotesNote: Even though the html element is the root element, it does not contain the doctype element. The doctype element must be placed before the html element.
Required AttributesDTD indicates in which HTML 4.01/XHTML 1.0 DTD the attribute is allowed. S=Strict, T=Transitional, and F=Frameset.
