It's amazing that despite how simple and fundamental all of these things are, very few people coding HTML get them right.

Code will be well-formed and be easier maintained, as certain aspects will always be consistent. More chance of your document being correct. If your HTML isn't't well-formed, sometimes browsers have to make a guess as to how it should be rendered. It may work fine now, but maybe browsers will change how they guess.

When combined with using valid CSS, your documents will generally load a lot quicker, and render properly on a wide variety of browsers. Goes a long way to improving accessibility (although don't make the mistake of thinking your pages are accessible just because they are valid XHTML). There are three different document types you can use for XHTML. You must specify which kind of document right at the top.

XHTML 1.0 Strict - This is a well-formed XHTML document that uses no deprecated tags such as basefont, center, font, s, strike and u. It also does not allow deprecated attributes such as bgcolor, align, valign.

XHTML 1.0 Transitional - This is by far the most widely used document type. It allows the use of the deprecated tags listed above. It doesn't allow usage of frames.

XHTML 1.0 Frameset - This is the same as the transitional document, but allows frames. It is recommended that you use XHTML 1.0 Strict whenever possible.
