not available in this open source version).
Add class 'bullet-list' to ul elements, simplify CSS

The list-style is now set to 'none' by default, and the decoration
is only added to ul elements with the class 'bullet-list'.
Define same max-width as article for header and (responsive) nav
Adjust horizontal position of the nav to account for larger content area

Reduce font size in bullet lists, restore original width of content area

I also removed the italic style, and restored the position of the nav.
Remove redundant style: display block within inline-block
Remove redundant style: partial reset following reset
Use class 'contents' for nav styles in CSS

I also hardened the selectors where possible, using child selectors '>'
instead of the general descendant selectors ' '.
