ExampleA simple HTML document, with the minimum of required tags:
|
The <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.
The xmlns attribute is required in XHTML but 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.
Note: 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.
DTD indicates in which DTD the attribute is allowed. S=Strict, T=Transitional, and F=Frameset.
Attribute | Value | Description | DTD |
---|---|---|---|
xmlns | http://www.w3.org/1999/xhtml | Defines the namespace to use | STF |
dir, lang, xml:lang |
