Fixed separator navbar/Reverted indom container

It now scrolls with the header. Additionally I reverted my changes with the
indom container, due to the logic being needed.
Made separator/footer (icons) larger

The separator is larger, as well as the text in the footer.
Additionally, the footer now works on smaller screens
(but email isn't there... just icons)
