HTML Basics: Terminology:

Tags, content and presentation:

In its most basic form, an HTML document consists of text, enclosed in tags. These tags (more accurately, these elements ) describe the meaning of the text they contain, rather than how the enclosed text should be displayed.

This concept is called content-based markup, as opposed to presentational markup.
Content-based markup allows device independence; knowing the meaning of a piece of text allows a browser to render it as good as possible on the platform it is running on. With presentational markup this is impossible.

Without knowing why a string of text must be displayed in red 20 points Helvetica, you can't pick a good alternative way to display it on a screen where this font isn't available.

Using tags:

An element, when used in a document, consists of an opening and a closing tag. The closing tag is not always used. It might be optional, or even forbidden. The group of elemens which have opening and closing tags are referred to as container elements , and the group of elements without closing tag as empty elements .

 Container tags may not overlap each other. Always close the innermost container first, if you are nesting them. An opening tag can have certain attributes . These provide extra information about the tag and the text they enclose, if any. For example, the A tag has an HREF attribute which defines where the anchored text is a link to.

The attribute may have a value, although this is not necessary in all cases. If it has a value, it is specified in the "name=value" form. The value must be enclosed in quotes if it contains anything more than letters, digits, hyphens and/or periods. In all other cases, quoting is optional. The maximum length for an attribute value is 1024 characters, including the quotation marks (if used).

The generic structure:

The document can be divided in two parts, the head and the body . The document head provides information about the document, for example it.........
