Using the W3C’s Validation Services
To use the W3C's validation services to validate HTML code the DOCTYPE declaration is required. This goes at the very top of your HTML coding. To learn more about where the DOCTYPE declaration goes, see our HTML Document Structure article. The DOCTYPE declaration sets what HTML specification standard the document is coded for so the browsers and validators know how to process HTML code.
Leave the following items at their default:
* Character Encoding
Will check that you included the character encoding meta tag and if it is coded correctly.
* Document
