1.
 - Set a minimum page height, client doesn't want to see the next
 section when tabing through pages.
 - can the home page, which only has two sentence not have a minimum
  height set? Yes
 - home page graphic image doesn't seem to be wrapping correctly in
  mobile view.
 - Make site Nav titles (Home, Services, Portfolio, and Contact Us)
  BOLD when in the sub pages for that section.
 - Reduce the height vertical line separating the page titles, more
  like the main nav.
2.
 - scroll to page home Sub-level top of page position - when
  clicking one of sub-nav tabs it will go to the same scroll position
  that clicking on the primary navigation tab does (ie top of page).

*. An additional fix was needed for the header image which wasn't
  properly resizing into mobile views
