- 2. 2 OVERVIEW: HTML-What is it? HyperText Markup Language, the authoring language used to create documents on the World Wide Web. It defines the structure and layout of a Web document by using a variety of tags and attributes. The correct structure for an HTML document starts with <html><head>(enter here what document is about)</head><body> and ends with </body></html>. All the information to be displayed on the Web page goes between the <body> and </body> tags. There are hundreds of other tags used to format and lay out the information in a Web page.

To attract users to your page, you should write a clear and concise title that describes what the page is about. The <html> tag should start at the beginning of the document and end after the close of the body element. The <head> element provides useful, but hidden, information about the page. The <title> element is also found within most HTML documents. The <body> element encloses the displayable content of the HTML documents.
