There are lots of divs in that page; I just had to look for the "human-readable" text to see where the content was. You can expect the other pages to be similar in format.
There is a bunch of styling information in the head of that page which will also want to be copied to the stylesheet. Check all of the class or id tags in the content, and if they don't have styling right there, look at the top of the page for the rule that styles that class/id.
Style rules that apply only to the header or navigation probably don't need to be directly copied, as the styling involved will be applied to different elements with different ids.
