CSS
|
CSS,
or Cascading Style Sheets, create templates for
web sites. Style sheets provide structure to web sites
independent of their content. Thus, you can define an
HTML tag so that it will appear the same through a web
site You won't have to trust your memory as much! As cascading
style sheet 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
|
DHTML is a combination of HTML, style sheets, and
JavaScript. It adds a touch of interactivity to static
webpages. That is, it creates animation of 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 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 complementary colors.
HTML is static: the user does not interact with it. With
the increasing need for interactivity, HTML is transitioning
towards CSS and XHTML.

XHTML
|
Many
of the newer technologies (Web TV, palm computers) pose
problems for HTML. To accommodate these technologies and
go beyond the ability of HTML, we are gradually moving
towards 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 codes:
-
have
a beginning and an end
-
must
be written in lower case
-
place
atttribute values in quotes
-
use
correct nesting
