W3C - HTML & CSS Markup Validation...
Designing a webpage to be compliant for any markup language is time consuming but can result in fewer browser compatibility issues. Checking a page for validity means that certain rules are being followed.
Even if a webpage is rated as valid utilizing correct markup language, it's no guarantee that the webpage is a good page, however an invalid markup result has no chance of being good at all.
it's also a good idea to check the validity of style sheets that are used in a web site as well. With the various web browsers used currently, not all CSS rules will work which will affect how the webpage is displayed.
