Currently i want to show my navbar when i am scrolling on my webpage and hide my navbar when i am scrolling back. I search all over on Google, and i could not find something that could help me. I am surprised that this wasn't on the web yet. Maybe i didn't search good enough, however, after several hours of frustrating myself, i decided to get some help from the pro's here. ;-)

Would appreciate any help!

<body>
<nav>
     <ul>
          <li><a href="#">Help</a></li>
     </ul>
</nav>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"</script>
</body>


nav{
    position: fixed;
    padding: 30px 70px;
    width: 100vw;
    height: 10vh;
    background: black;
    transition: .5s ease;
    z-index: 5;
}

nav ul{
    float: right;
    margin-right: 100px;
    padding: 0px 40px;
}



$(window).scroll(function () {

    var scroll = $(window).scrollTop();
    var p = $win.scrollTop() / max;
    var x = window.matchMedia("(max-width: 800px)")

    console.log(scroll);
        if (scroll > 0) {
            $('nav').css({
                "top": "0%",
            });
        } else {
            $('nav').css({
                "top": "-25%",
            });
        };
});

I think you mean something like that https://www.w3schools.com/howto/howto_js_navbar_slide.asp

Or something like this:

let lastScrollTop = 0;
function scrollFunction() {
  scroll = document.body.scrollTop || document.documentElement.scrollTop;
  if (scroll > lastScrollTop) // Scrolling Down
    document.getElementById("navbar").style.top = "0";
  else // Scrolling Up
    document.getElementById("navbar").style.top = "-50px";
  lastScrollTop = scroll;
}


window.onscroll = function() {scrollFunction()};

let lastScrollTop = 0;
function scrollFunction() {
  scroll = document.body.scrollTop || document.documentElement.scrollTop;
  if (scroll > lastScrollTop) // Scrolling Down
    document.getElementById("navbar").style.top = "0";
  else // Scrolling Up
    document.getElementById("navbar").style.top = "-50px";
  lastScrollTop = scroll;
}

  margin: 0;
  background-color: #f1f1f1;

#navbar {
  background-color: #333;
  position: fixed;
  top: -50px;
  width: 100%;
  display: block;
  transition: top 0.3s;
}

#navbar a {
  float: left;
  display: block;

  text-align: center;
  padding: 15px;

#navbar a:hover {

<div id="navbar">

  <p><b>This example demonstrates how to slide down a navbar when the user starts to scroll the page.</b></p>
  <p>Scroll down this frame to see the effect!</p>
  <p>Scroll to the top to hide the navbar.</p>

And someone already did it in jQuery How can I determine the direction of a jQuery scroll event?
