CSS
|
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 wegbsite. 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--win.

DHTML |
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 open or close menus upon the user moving the
mouse. It's biggest use is for mouseovers and image/layer
transitions.

HTML |
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.

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
