Header Navigation
The navigation for a blog doesn't have to have any more than links to the home page, the entries list and the archive(s). The navigation shown above has centered inline block links which return to two or more lines on devices with narrow screens.
The optional subscriber signup and search functions open in a modal window are pretty much essential for inserting on every blog page.
The signup form requires MailChimp and the search function requires a Google Custom Search ID.
