The second tag that must appear on every document is this one. It can contain special information about the document as well as the title of the document. The title may be the same as your first headline, but it doesn't have to be. It's important for several reasons. It usually appears at the top of the document in your browser.
Most browsers use the title when they make a bookmark.
Unfortunately some people making Web documents either aren't aware of this, or don't care, but if you want your document to be remembered by others, give it a meaningful title. Everything you've done on your HTML document up to now would appear between the two body tags. Go back now and make your last practice document into a real HTML document. For the most part it should. If you did, these will appear at the top of your document when you view it in a Web browser.
