which lets you keep using some old practices from HTML4, and there is a<br />
'strict' version, which is the one you need to use to get most of XHTML's<br />
benefits.<br />
The web's standards body, the W3C, runs an HTML validator at<br />

What Does All This Mean to Me?<br />
You might be wondering at this point why exactly you need to know about<br />
the different kinds of HTML. Well, as ever, the answer is that you need to<br />
choose one before you start developing your website. You have to be aware<br />
of which versions your tools support to know whether your tools can work<br />
together, and you should aim to pick the kind of HTML that will be most<br />
suitable for your site.<br />
At the moment, XHTML is recommended for most websites, simply because<br />
it makes the whole process much easier, especially if you use an editor that<br />
saves to XHTML automatically. The only situation in which you should really<br />
keep using HTML4/DHTML is if you're designing a web application instead of<br />
a web page. If your site is, like 99% of the sites on the web, designed to give<br />
information more than it is designed to do anything else, then you should be<br />
using XHTML, preferably the strict version.<br />
Chapter 12: Clean Page Structure: Headings and Lists.<br />
When HTML started, people put all sorts of things on their pages: there was a<br />
tag to say which font you wanted your text to be in, a tag to say you wanted<br />
it to be in the center of the page, and so on. Now, though, that way of writing<br />
pages is out-of-date and very inefficient compared to keeping content and<br />
style separate using CSS.<br />
What is CSS?<br />
CSS stands for Cascading Style Sheets – it is basically a way of saying once<br />
what you want your pages to look like, instead of having to repeat it in HTML<br />
all the way through the document. In old style HTML, for example, this kind<br />
of code was a relatively common sight:<br />
