When tables are used to represent logical relationships
among data -- text, numbers, images, etc., that information
is called "tabular information" and the tables are called
"data tables". The relationships expressed by a table may be
rendered visually (usually on a two-dimensional grid),
aurally (often preceding cells with header information), or
in other formats.

either the start or end of an element, but not the element
A tag line is a slogan, catch phrase or sentence that is
closely associated with a site. A tagline may appear near, or
next to, a logo.
Tag soup web pages are like a sleek sports car on the
outside, but when you open the hood, all you see is baling
wire, duct tape, and hamsters running on wheels. If all you
want to do with a sports car is look at it, that's fine, but
if you want to drive it, it is nice if it has an engine and
suspension that lived up to its appearance. In other words
tag soup is improper use of
header tags, blockquotes, overlapping constructs. It is
markup that looks like
markup but the creator didn't know or respect
rules for the
vocabulary. In effect a soupy collection of text and markup.
Presentational markup such as

ingredients in tag soup. The <font> element

A taxonomy is the study of the general principles of
scientific classification. Information architects use this
word to refer to labeling systems and nomenclature of things
like the sections of a website. It is a collection of
controlled vocabulary terms organized into a hierarchical
structure. The word taxonomy is from Greek 'taxis' means
the arrangement or division and 'nomos' meaning law. A good
taxonomy takes into account the importance of separating
elements of a group (taxon) into subgroups (taxa) that are
mutually exclusive, unambiguous, and taken together, include
all possibilities. In practice, a good taxonomy should be
simple, easy to remember, and easy to use.
A template is a page that serves as a pattern for others
like itself. Dreamweaver templates take the concept of the
template further, adding a measure of power and ease: The
pages from the template can be updated automatically, all at
once, just by updating the template itself. Therefore, a
Dreamweaver template is an
page but a special type of HTML
page. Special markup inserted by Dreamweaver makes it
possible for the template and its child pages (the HTML
pages made from the parent template) to be connected in
such a way that an update to the template updates all

they keep in mind when using it. It gives insight into cognitive
processes. For more information consult
A transcript is a text equivalent of audio content that
includes spoken words and non-spoken sounds like sound effects.
It is akin to the notation used for a play. Transcripts are
often not verbatim accounts of the spoken word, but contain
additional descriptions, explanations, or comments that may
be useful. Transcripts are helpful to the deaf, hard of hearing
and many others. They allow anyone that cannot access content
from web audio or video access a text version instead. Also a
transcript can serve as the base for captioning.
Typography is the balance and interplay of letterforms on
a web page. It helps the user understand the form and absorb
the substance of the page content. It is important in both
visual and verbal communication.
