Positioning a Navbar
Place these CSS elements (position: fixed;, top: 0;, and width: 100%;) in your top-most section whether it is a UL, DIV, or NAV tag. Set an .active class on a tab to identify the current page the user is on. And add other elements such as dropdowns and search bars.
Full CSS Only Navbar
Added dropdown functionality to the News menu (navbar) item. Check out the page source under the div-id=navbar5 section of code for the requisite code. Follow the dropdown and dropbtn classes in the styles section for the relevant CSS.
Added a search form to the navbar for completeness. And added a media query to stack the menu vertically on small screens. Again, see the page source for the code.
