You have to know HTML in order to know where things end. Otherwise, you will see nested paragraphs here: <p>Hello <p>World</p>!</p> when it’s actually two consecutive paragraphs, an exclamation mark outside of any paragraph, and a closing p tag without an opening counterpart. And when you do know HTML, you might as well omit optional tags. If you think that HTML syntax is crazy, I won’t blame you, and you might consider XHTML instead, but you should be prepared for different woes.
