Improved post header and footer

Headers
- mobile cover image working

Footers

Correct themeing for off-canvas menu

The off canvas menu now matches the primary colors of the rest of
the site (pure black).

`_players.scss` has also been refactored to make it more maintainable
and the styles on the logo were tweaked to improve spacing.
