Section element - Example error I see that there is a mistake on the section element (http://www.w3.org/TR/html5/sections.html#the-section-element) in the last code example about the book authors. You can see that the CSS used for render headings is an h1 element, but on the HTML it is using an h3 element. So maybe the correct for CSS is "section.chapter h3" and "section.appendix h3".
The example has been removed in http://www.w3.org/TR/html51/semantics.html#the-section-element
