title: Can a HTML document be created without the <html> tag?
body: <p>I found this sample HTML code on gitHub - <a href="https://github.com/jasondavies/d3-cloud/blob/master/examples/simple.html" rel="nofollow">https://github.com/jasondavies/d3-cloud/blob/master/examples/simple.html</a> and noticed that this page has no <code>&lt;html&gt;</code> and <code>&lt;/html&gt;</code>  tags and no <code>&lt;/body&gt;</code> tag. I was told that these were optional. I understand <code>&lt;tag /&gt;</code>, but how can one create an html document without the <code>&lt;html&gt;</code> tag? What is going on in this example?</p>
