PRDV401: Introduction to JavaScript I

The Hypertext Markup Language (HTML), developed in the 1990s, is a language for transmitting global hypertext documents. HTML is a "markup language" that defines the structure of a document using information such as tags and text. A web browser reads this information and displays a webpage. In this article, we look at a brief introduction to HTML. Then, we will focus on the structure of an HTML document, mandatory and optional tags, and attributes. As you read these sections, pay attention to the rules for writing HTML. For example, an HTML5 document must contain four basic tags enclosed in open "<" and closed ">" brackets.
