HTML Tag Reference Numbers
© 2012, Martin Rinehart
Reference numbers are from the source documents, where reference numbers exist. For HTML 1 (Berners-Lee's original) the tags are numbered in the order in which they appear in the document. For HTML 3.2 see our numbered 3.2 TOC.
HTML 5: As of 20120313 the numbers in the W3C HTML 5 standard and in the WHATWG Living HTML standards were the same. In most cases these numbers remain the same in the more recent standards.
