 This ICON at the right bottom of any page of this site means that we were authorized to use the icon, as a claim of HTML validity of the page code.
By click on it you'll be link to the W3C Markup Validation Service in order to verify it's validity.
The World Wide Web Consortium (W3C) is an international consortium where Member organizations, a full-time staff, and the public work together to develop Web standards. |
 One of the important maxims of computer programming is:
Be conservative in what you produce; be liberal in what you accept.
Browsers follow the second half of this maxim by accepting Web pages and trying to display them even if they're not legal HTML. Usually this means that the browser will try to make educated guesses about what you probably meant. The problem is that different browsers (or even different versions of the same browser) will make different guesses about the same illegal construct; worse, if your HTML is really pathological, the browser could get hopelessly confused and produce a mangled mess, or even crash.
That's why you want to follow the first half of the maxim by making sure your pages are legal HTML. The best way to do that is by running your documents through one or more HTML validators.
A lengthier answer to this question is also available on this site if the explanation above did not satisfy you.
