CSS

/*

#Navbar collapse
Use flex column to stack the navbars on top of each other.

#The standard navbar
Use order-{size}-last to make it appear under the contact links when on a medium screen and up.

#The contact links
Use order-{size}-first to make it appear over the navbar when on a phone/ipad.

#Other
Use Fontawesome or anyother icon package to style the contact links.
