HyperText Markup Language (HTML)

• HTML is a tagged language with a tag set specified by the World Wide Web Consortium (W3C).
• An HTML document begins with the tag <html> and ends with the tag </html>.
• HTML imposes structure on a document in the form of <head> and <body> elements. Both the head and body themselves consist of elements composed of text surrounded by tags.
• The combination of a beginning tag, body, and closing tag is called an element. The element body may be text or it may consist of other elements.
• element syntax is:
  

  <tagName *[attributeName="value"]> element body </tagName>

  Attributes typically define colors, positions, links, ids, relationships, and event-handlers.
• Cascading style sheets, discussed later in these notes, are taking over many of the traditional uses of tag attributes in earlier versions of HTML.
