, an HTML element
(instance) in terms of SGML
is the complete sequence of a start tag (with attributes and their valuess), any embedded HTML content, and the end tag. A special case is empty elements that don't have contents and end tags. Due to the constraints of the DTDss
, various parts, including start and end tag, may be omitted in HTML
, but not XHTML
It is often misnamed "tag", in an ugly kind of pars-pro-toto.
