What is the HTML validator?

This FAQ will help you to use the HTML validator

Hypertext Markup Language, or HTML, is the language of the internet. HTML, along with CSS, controls what your website is, and how it looks. These days, with growing computer literacy, its more and more common for people to write their own websites. If you’ve chosen to do this, the HTML validator will check your content to make sure there are no errors, ensuring that your site displays exactly how you want it to.
