I tried adding a margin-bottom: 24px and a padding-bottom: 24px; to the header with no luck. It just needs some breathing room between the title of the page and the header
It's not possible to add margin/padding to the navbar due to the way it's positioned. To "fix" this try adding some margin-top to the .container-fluid class. Right now the margin is only 90px.
