How do you define an HTML Docytype tag?
I'm taking the code challenge, and have inserted <!DOCTYPE html> when asked to write an HTML doctype, and I keep getting this error message that I must define the HTML Docytype tag. How do I do that?

Is there anything wrong with doing all lowercase like the rest of the tags so like: <!doctype html>

3,247 PointsSumming up a few points: The DOCTYPE declaration doesn't need a closing tag (technically, it's not a tag, it is a Document Type Declaration). In HTML, you may use it in lowercase as well, but it indeed is case-sensitive, so beware.
