Online HTML Validators
Online HTML validators validate pages that are already on the Web. They send the results to you via email, or do it immediately in your browser.
The W3C Markup Validation Service
This is the validator I use. It validates HTML and XHTML against the standards. I especially like that I can upload a file to be validated, so I don't have to post something until it's completely correct.

Alpine HTML Validator
The interesting thing about this validator is that it will generate a repaired file for you to upload that fixes the problems found.

The results can be a little confusing, but this validator does a good job of showing you what you're doing wrong.
