Validation

HTML Validation

You can check the HTML code on each web page by using the W3C's on-line validator at:

http://validator.w3.org/

The validator is easy to use. Either enter the URL of your webpage or browse to a web file on your computer and click on the "Validate" button.

You must have a valid doctype statement on the page otherwise the validator will fail.

If your page is compliant it will report no errors. Otherwise it will list the errors and provide a link with an explanation.

Accessibility

You can get an accessibility report from Bobby at:

http://bobby.watchfire.com/bobby/html/en/index.jsp

Much of the report requires you to make manual checks, so you need to have a good understanding of HTML and disability issues to use this validator effectively.

Browser Compliance

You can check for browser compliance using Dr HTML at:
