CSS: fix misaligned inline nav, simplify

Fixing the misaligned inline nav using "inline-block" also made it
obvious that I can simplify compound selectors. The max number of
compound selectors has dropped from 4 to 2. Update stylelint configs to
reflect this.

Also fix containment to reflect a prior change (webmentions are a
section, not a footer.)
