Oh I see. perfect, thanks. Just one quick dumb question, how is xhtml different from html? I know xhtml is a blend of html and xml, as a user stated above, but I don't know what that means.
Also, I can make web pages using xhtml instead of html right?
Yes, you can. They're basically synonymous except that XHTML is "extensible" (hence the X) and is easily usable with Javascript. In fact, if you were to build an AJAX application, it's basically required, to work well, that it manipulate an XHTML document -- not an HTML document. XHTML defines and very well-formed structure, whereas HTML just kind of lays things out and styles them, which is generally bad practice when developing applications. You want to separate your style from form from layout from logic and functionality.
Code in XHTML -- if you decide to add AJAX or even basic JS stuff to it you won't have a problem. But if you code in HTML then decide to add Javascript later you'll have to convert to XHTML.
Consider this scenario, too:
One of our products gets quite a few support tickets because people don't follow instructions. We sell a Javascript library that users can add to their site to add instant address verification (called LiveAddress) when the user types their address in a form at checkout.
Some people use HTML but the AJAX stuff requires XHTML. It just doesn't work with HTML declarations and markup. For example, we require users to add this:
<?xml version="1.0"?>
for IE6 compatibility, and then this doctype:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
So as you can see, XHTML has numerous advantages at the current time.
