From w3.org:
The World Wide Web Consortium (W3C) is an international community that develops standards to ensure the long-term growth of the Web. Read about the W3C mission.
Having a web page that is W3C compliant definitely isn’t required. However making sure your markup is W3C compliant ensures that it works the best with the widest array of computers and other devices. W3C compliance will give the web site owner piece of mind in knowing that their HTML is held to the highest standard in the industry. All W3C compliant sites are entitled to display the validation badge. Including this mark of excellence on your site shows your users that you take their experience seriously and strive for nothing but the best.
