</div>

/* When the user scrolls down, hide the navbar. When the user scrolls up, show
the navbar */

window.onscroll =
function() {
var currentScrollPos = window.pageYOffset;
if
(prevScrollpos > currentScrollPos) {
document.getElementById("navbar").style.top = "0";
} else {
document.getElementById("navbar").style.top = "-50px";
}
prevScrollpos = currentScrollPos;
}
