XHTML Validation

One of the main points you have to consider when you write an XHTML Web page is whether it is valid XHTML according to the DTD you have chosen (XHTML Strict, XHTML Transitional, or XHTML Frameset).

This might seem like a pain. Before, you could just write markup and not bother about the rules as long as the browsers displayed a page more or less like you wanted. But considering the benefits you receive for XHTML validation, it is worth it to check.
