Introducing HTML
This chapter provides an introduction to using HTML to create simple Web pages suitable for interfacing with PHP applications. Several examples show how to modify the appearance of a document by using HTML tags and their attributes.
1.1 Introducing the Tools
1.1.1 What Is an HTML Document?
HTML is an acronym for HyperText Markup Language. HTML documents, the foundation of all content appearing on the World Wide Web (WWW), consist of two essential parts: information content and a set of instructions that tells your computer how to display that content. These instructions—the “markup,” in editorial jargon—comprise the HTML “language.” It is not a programming language in the traditional sense, but rather a set of instructions about how to display content in a Web browser. Ideally, online content should look the same regardless of the browser being used or the operating system on which the browser resides. This goal of complete platform independence is achieved only approximately in practice. Every HTML document should contain a minimum of four elements:
These elements define the essential parts of an HTML document: the document itself, a heading section, a title section, and a body. All four elements should be included even if they don’t enclose any content. Every HTML element is defined by one or two tags—usually a start tag and an end tag. Tags are always enclosed in angle brackets: . End tags start with a slash (/). A few HTML elements have only one tag.
The four basic elements are organized as follows within an HTML document:
