“Hint: Your new div element should have a closing tag.”
The hint is exactly right. A div element has both an opening <div> tag and closing </div> tag. Notice that a tag always starts with < and ends with >. Do both of the tags that you added start and end with the proper characters?
If they didn’t, how would you nest other elements inside of them? How would you tell where they start and end?
UPDATE: I think maybe I read your question wrong? You are asking about two closing tags? I’m not sure what you mean by this. I never said they needed two closing tags. I said a div needs an opening and closing tag. I think that’s what you intended to do, but you didn’t get the syntax right. You are missing some angle brackets.
Nesting is putting one element inside of another. For example, up to this point you have nested several meta elements, the title element, and a link element in the head element. Do you see how those nested elements are in between the opening and closing head tags?
Ahh, I think I understand now. Yes, there will be two </div> closing tags, one right after the other because you are nesting one div inside of another. The important thing is that each of those divs has their own pair of opening and closing tags.
