The importance of the Doctype
HTML follows certain rules-these rules are contained in a Document Type
definition file, otherwise known as a DTD. A DTD is an XML document
that explains what tags, attributes, and values are valid for a
particular type of HTML. And for each version of HTML, there’s a
corresponding DTD. By now you may be asking, “But what’s all this got
to do with CSS?”
Everything, if you want your Web design search engine optimization
to appear correctly and consistently in Web browsers. You tell a Web
browser which version of HTML or XHTML you’re using by including what’s
called a doctype declaration at the beginning of a Web page. This
doctype declaration is the first line in the HTML file and not only
defines what version of HTML you’re using but also points to the
appropriate DTD file out on the Web. When you mistype the doctype
declaration, you can throw most browsers into an altered state called
quirks mode.
Quirks mode is browser manufacturers’ attempts to make their software
behave like browsers did circa 1999. If a modern browser encounters a
page that’s missing the correct doctype, then it thinks “Gee, this page
must have been mwritten a long time ago, in an HTML editor far, far
away. I’ll pretend I’m a really old browser and display the page just
as one of those buggy old browsers would display it.” That’s why,
without a correct doctype, your lovingly CSS-styled Web page may not
look as they should, according to current standards. If you unwittingly
view your Web page in quirks mode when checking it in a browser, you
may end up trying to fix display problems that are related to an
incorrect doctype and not the incorrect use of HTML or CSS.
Fortunately, it’s easy to get the doctype correct. All you need to know
is what version of HTML you’re using. In all likelihood, you’re already
creating Web pages using HTML 4. You may even have started using XHTML
for your Web sites.
The most popular versions of HTML and XHTML these days are HTML 4.01
Transitional and XHTML 1.0 Transitional. These types of HTML still let
you use presentational tags like the <font> tag, thereby
providing a transition from older HTML to the newer, stricter type of
HTML and XHTML. Although it’s best not to use these tags at all, they
still work in the Transitional versions, so you can phase out these
older tags at your own pace. In the strict versions of HTML and XHTML,
some older tags don’t work at all.
If this entire discussion is making your head ache and your eyes slowly
shut, just make sure you use the proper doctype listed above, and
always make it the first line of your HTML file. If you want a basic
template to use when building either HTML or XHTML pages.
