Descriptive markup: Writing descriptive markup
Descriptive markup should be based on the (textual) content of the page. The web developer or content manager applies structure to this content from a repertoire of HTML elements that each has its own purpose.
The content provided by the author is rarely one long piece of text. Often the author has already divided the text into paragraphs, headings and subheadings. This structure can easily be translated into a descriptive structure.
