CSS, or Cascading Style
Sheets, create templates for websites. Style sheets provide
structure to websites independent of their content. Thus, you can
define an HTML tag so that it will appear the same through a website.
You won't have to trust your memory as much! As cascading style
sheets implies, more than one style sheet can be used on the
same document, with different levels of importance. If you define
conflicting styles for the same HTML tag, the innermost definition--the
one closest to the tag--wins.

DHTML is a combination
of HTML, style sheets, and JavaScript. It adds a touch of interactivity
to static webpages. That is, it creates animation or interaction
on a webpage. DHTML is often used to openor close menus upon the
user moving the mouse. It's biggest use is for mouseovers and image/layer
transitions.

The standard coding language
that creates the display of information on a webpage. HTML can create
a simple or complex display. The key to good web design is to create
a clean visual display, consistent theme via the use of complementary
colors. HTML is static: the user does not interact with it. With
the increasing need for interactivity, HTML is transitioning toward
CSS and XHTML.

Many of the newer technologies
(WebTV, palm computers) pose problems for HTML. To accommodate these
technologies and go beyond the ability of HTML, we are gradually
moving toward XHTML. XHTML is written in XML but very similar to
HTML. The tags and attributes are almost all the same but it is
extremely picky about code specification. XHTML requires that all
codes:
- have a beginning and end
- must be written in lower-case
- place attribute values in
quotes
- use correct nesting
