From a technical point of view, the document
interpretation is more appropriate.
When we examine the elements of its construction, a web document can consist of
up to three layers??”content, presentation, and behavior??”as illustrated in Figure
1.1.
The content layer is always present. It comprises the information the author wishes
to convey to his or her audience, and is embedded within HTML or XHTML markup
that defines its structure and semantics. Most of the content on the Web today is
text, but content can also be provided through images, animations, sound, video,
and whatever else an author wants to publish.

The presentation layer defines how the content will appear to a human being who
accesses the document in one way or another. The conventional way to view a web
page is with a regular web browser, of course, but that??™s only one of many possible
access methods. For example, content can also be converted to synthetic speech for
users who have impaired vision or reading difficulties.
