A Short Introduction to the
Interesting WWW Links
Chapter Ia: HTML
Hypertext Markup Language
(in its many variants and bastardizations) is the code used to construct
all the WWW pages (including this one).
If you're unsure which HTML features your browser
supports check the HTML test set,
I personally favour using Emacs with HTML-helper-mode
or PSGML to edit HTML although others may prefer some other
editors, of which some claim to be
WYSIWYG and often create
barfed up HTML, which doesn't follow any standard and therefor won't pass any validator. Or alternatively you could also use one of the numerous filters or converters
to create HTML
For information about good authoring styles, take for a
example look at:
And for even more hints about WWW development, following sites give good
There's also couple humorous HTML authoring guides...
- HTML 2.0
- The only HTML that has yet been made into RFC, no fancy stuff.
- HTML 3.0
- Now expired Internet draft, which introduced all kinda neat things
like tables, math and style
- HTML 3.2
- W3C's previous version of HTML,
representation of common practice around 1996 (eg. tables, applets,
text effects). Somewhat limited compared to HTML 3.0 draft.
- HTML 4.01
- W3C's latest version of HTML featuring
style sheets, scripting,
object embedding and improved internatinazation and accessibility.
- XHTML 1.0
- HTML as XML document type. W3C recommendation.
- Very strict HTML version based on HTML 4.01. There's also User's Guide
available for it.
General Markup Language (SGML)
- HTML is a SGML document type.
- Extensible Markup Language (XML)
- XML is intended to be a standard
to make it easy and straightforward
to use SGML on the Web: easy to define document types, easy to author
and manage SGML-defined documents, and easy to transmit and share them
across the Web.
- Not really part of HTML itself nor a just one standard, but a nice
method to control how browsers (provided they support stylesheets)
should render the pages.
Better check whether your HTML code is valid! Here's some tools for that,
for even more, see Web Design Group's

Validator, W3C validator checks your documents against one of the
several DTDs based on
the <!DOCTYPE>-declaration in the beginning of
