2.3 HTML Embedded Tags

You probably have noticed right away, perhaps in surprise, that the browser displays less than half of the example source text. Closer inspection of the source reveals that what's missing is everything that's bracketed inside a pair of less-than (<) and greater-than (>) characters. [the section called "HTML Tags"]

HTML is an embedded language: you insert the language's directions or tags into the same document that you and your readers load into a browser to view. The browser uses the information inside the HTML tags to decide how to display or otherwise treat the subsequent contents of your HTML document.

For instance, the <i> tag that precedes the word "Hello" in the simple example tells the browser to display the following text in italic.[1] [the section called "Physical Style Tags"]

[1] Italicized text is a very simple example and one that most browsers, except the text-only variety like Lynx, can handle. In general, the browser tries to do as it is told, but as we demonstrate in upcoming chapters, browsers vary from computer to computer and from user to user, as do the fonts that are available and selected by the user for viewing HTML documents. Assume that not all are capable or willing to display your HTML document exactly as it appears on your screen.

The first word in a tag is its formal name, which usually is fairly descriptive of its function, too. Any additional words in a tag are special attributes, sometimes with an associated value after an equal sign (=), which further define or modify the tag's actions.
