Fix a long-standing issue:

Some macros (Nd, Oo) can contain blocks but rendered as elements that
can only contain phrasing content, resulting in invalid HTML nesting.
Switch them to <div>.
Also move the related "display: inline" style from the HTML to the CSS.

Reminded during a conversation with John Gardner.
