Once you learn about HTML, you can make your web pages do new and exciting things with some added extras. This section isn't meant to be comprehensive, but to give the user an idea of what else is out there. In this section, we'll discuss some of the useful add-ons or tools that can be used on a website. You may encounter the following:
  • Animated gifs
  • JavaScript
  • Java
  • Flash
  • CGI files
  • Miscellaneous scripts and whatnot
One more thing I'd like to mention here. If this bores you, skip it.

So far we've discussed HTML. It is the basic language of the internet, but there are other versions ow web programming making their rounds. One of the most commonly mentioned is XHTML. XHTML stands for EXtensible HyperText Markup Language. It is considered a very strict version of HTML, and it's almost identical to HTML version 4.01, the HTML currently used.

As noted by sites like Who is Hosting This and W3schools.com, the most important differences between HTML and XHTML are:
  • XHTML elements must be properly nested
  • XHTML documents must be well-formed
  • Tag names must be in lowercase
  • All XHTML elements must be closed
         Here's an image <img src="happy.gif" alt="Happy face" />
  • Attribute names must be in lower case
  • Attribute values must be quoted
  • Attribute minimization is forbidden
  • The id attribute replaces the name attribute
  • XHTML documents must have a DOCTYPE declaration
It's not a hard transition from HTML to XHTML if you learned HTML correctly.

Another term you may run across is XML. XML stands for EXtensible Markup Language. It is only made to describe data. It will not format that data for you, but is used with HTML to send info from place to place. It is not a replacement for HTML at all. It is very similar to HTML however.

XML uses tags, but these tags aren't defined by the computer. They are defined by the creator of the page. Because of this, XML doesn't "do" anything, but it makes info compatible between different systems.
