"The First Book: Go ahead, it won't bite. Well... maybe a little. More a nip, like. A tingle. It's pleasurable, really. You see, it keeps on opening. You may fall in. Sure, it's hard to get started; remember learning to use knife and fork? Dig in: you'll
never reach bottom. It's not like it's the end of the world -- just the world as you think you know it."
The target attribute specifies where to open the linked document.
I know. That's why this use doesn't seem to make sense to me. Maybe it's useful if you have a ton of such links and they'll all open into the same window as the first? In any case, it can safely be left out. Links open fine without a target attribute.
